Three Questions! (December 14)

SA node

1. Lately I have turned in my Frankenstein Essay and almost finished reading The Picture of Dorian Gray in English. In Anatomy, we started the Cardiovascular System and got all of our packets.
2. I've learned that a baby's heart starts beating alone, without the help of an electrical impulse! Pretty crazy stuff!  This is due to a piece of tissue, called the SA node, that regulates the pace of the heart, the pacemaker. When someone's heart beats irregularly, a pacemaker is inserted that takes the place of the SA node.
3. Next week I play on studying like crazy for my finals in every class. What a joy! And on top of all of that, I just got sick. High school is flying by, but I'm looking forward to a break from this semester .

Three Questions! (December 7)

Skyfall Poser- Because who doesn't love Daniel Craig?

1. Lately I've been pretty overwhelmed with school. The last couple weeks have been pretty intense, and I still have finals to study for. I've completed my anatomy packets and studied to the Endocrine/ Reproductive System test. I also went to see Skyfall this weekend, which I enjoyed. I recommend seeing it.
2. I learned how hormones work, and what happens when they are hyper/hypo secreted into the body. I also learned that the reproductive systems are SUPER complicated and childbirth is pretty..graphic. In math, we started chapter 7. So far we've done area between two curves and 'integrals as a net change'.
3. Next week I need to finish writing my written portion of my French final, finish my Frankenstein Essay, and keep on with my reading of Picture of Dorian Gray. I'm really liking it so far. Oscar Wilde's writing is pretty awesome. I also must take the end of course exam for English. It's pretty stupid that we have to take a test over material that we have no foreknowledge about. Pretty stupid indeed.

Hormones & Stress!

Student Stressing

As well all know, stress can be unhealthy and quite frankly, stressful. Even animals endure physical and physiological stress. But what is stress? Stress is a condition that the body is in due a stressor, which is a factor that changes the body's internal environment that can threaten life. Short term stressors are those that cause the body so put necessary processes, such as digestion, healing a wound, and fighting infection on hold for a few moments, a "fight or flight" response. This can be when you need to make a split second decision to save your life. Animals running from predators is an example of short term stressors where the body returns to its normal conditions after the response is initiated. A long term stressor is a chronic condition where the body is constantly under stress, usually psychological stress. Long term stress is dangerous to the body and can lead to high blood pressure, heart problems, ulcers, and premature death. The immune system is also compromised because of chronic stress and can lead to increased risk of infection.
There are many ways to reduce stress. These include deep breathing, relaxation, and mediation. For help with stress in school there are other strategies. Not that I am an expert in stress reduction (I have my fair share of school stress), but I have found some ways to reduce stress, at least for a little while.
1. Stay organized!- Knowing what you have to do helps the feeling of assignments and duties hanging over your head.
2. Relax, using deep breathing - as mentioned in the stress video we watched today, deep breathing can calm the body down and alleviate stress.
3. Have some fun- doing some school work before a fun day and some after makes you feel that you got something accomplished before something fun.
I have found these tips helpful but still have a long way to go! Stress is hard to get rid over, especially with finals week quickly approaching!

Three Questions! (November 30)

Endocrine System- Next Week!

1. This past week I've been super busy. I studied like crazy for the Nervous System test and got a little behind in math because of that. Then I did a bunch of math to catch up and started writing a Frankenstein Essay and started studying for my French final. Very busy indeed. Apparently these next few weeks aren't going to be any better. But I have to admit I would be bored without things to do (but maybe not this many things). Then I went to a French Club luncheon and the campus cleanup.
2. I learned a lot about how the brain works from my studies. I also learned partial fractions, tabular method, and more U substitution in Calculus. I also learned we're covering four chapters in three weeks in anatomy.
3. Next week, I'm planning on doing the same thing as last week. We're starting Endocrine System in anatomy, which should be fun. I will have to study for a math test on Tuesday, though. I also want to start making sure I've got everything covered for finals week.

Nervous System!

Parts of brain associated
with different senses

What does the brain do? That is the real question. It accomplishes so many things, it's hard to fathom. Your brain has a hard time figuring out what your brain does (ironic, right?). It is responsible for all of the motor responses to stimuli and has parts for speech, language recognition, smell, taste, and sight. Truly awesome. It tells everything in your body what do in a split second before it seems you have time to think, but your brain already noticed the stimulus, decided what to do, and responded to it. The brain does this via electrical impulses. Even though all of this information is known, scientist still have a lot to learn about the brain. They have learned most of what they know but studying brains that have gone wrong. By looking at the parts of the brain that have been affected by a disease, disorder, or damage, they can tell what the brain should be doing as opposed to what it is doing.
Cutting into a brain (as we did on Tuesday) all you see is bumps, ridges and white and gray matter. It doesn't seem like this matter can control everything you do, even involuntary functions like breathing, digestion, and pumping blood from the heart. That's what's so cool about it!
In the TED video, the neuroscientist, Dr. Taylor describes the events that unfolded after she had a stroke. She used to research mental illness, studying how cells and chemicals react in brains with schizophrenia and bipolar disorder. Then one morning she had a hemorrhage in her brain (a blood vessel exploded). Because of this she completely lost all control. She could not walk, talk, or remember everything from her past life. It's very interesting how one bursted blood vessel could affect all of this. This is in stark contrast to another part of the body. For example, in the arm, if a blood vessel were to burst, there would be pain, but it wouldn't lead to deterioration of function. The right and left hemispheres have different functions that map out every second of life by sensory information sucked in by the brain. The right hemisphere is very in the moment, like an adrenaline junkie. The left hemisphere is concerned with the past and future, thinking methodically and analytically. It organizes all of the obtained information into little filing cabinets and makes us individuals. The brain is an amazing, possibly the most amazing part of our body.

                        Check out this video, also from TED! It discusses the adolescent brain!

Three Questions! (November 23)

Playdoh Brain Model

Here's another installment of the weekly three questions. This week is special though, it's Thanksgiving break.
1. This was a short but awesome week in Anatomy. We first got to play with Playdoh again, something I haven't done in ten years. The playdoh brain helped us identify the structures and was fun to make, I must admit. Then, on Tuesday, we dissected a real sheep's brain which was way more cool than the playdoh brain. It really didn't smell that bad. I also went to Phoenix for the break to attend a concert and football game (against my will).
2. Lately I've learned most parts of the brain and the different functional areas. I've also learned how to do U substitution in calculus, and that Frankenstein's monsters isn't as bad as everyone thinks he is.
3. Next I plan to finish all the Nervous System coloring plates and finish reading Frankenstein. I also plan to get very familiar with the Nervous System for the test.

Three Questions! (November 16)

Euler

1. Lately I have started the Nervous System in anatomy. I'm pretty excited that we get to dissect a sheep brain on tuesday! Also, I have started reading Frankenstein in english and took another test in calculus. I have a Phantom of the Opera concert friday and saturday night too. It's been pretty fun learning that music. The choir people are really awesome (shout out to Brad).
2. I learned a lot from the brain video we watched in anatomy. It was really interesting to see what happens if the brain is damaged. In math we're doing more integrals using things with slope fields and Euler's method. I also learned Euler's is pronounced Oiler's.
3. Next week I'm planning on working on the nervous system coloring plates and dissecting that brain! I'm also planning on taking a break from school during Thanksgiving Break (we're going to Phoenix).

Neurophysiology Leech Lab

Leech opened
for dissection

The objective of this virtual neurophysiology lab was to record the electrical activity of individual neurons when mechanical stimulus is delivered through the skin of the leech. The we injected a fluorescent dye, called Lucifer Yellow, into the neurons the visualize their morphology.The cell was loacted  We identified the neurons based on their response to stimuli. First, we anesthetize the leeches so they won't move (not that they actually would in a virtual lab) and cut them open down the length of the leech. Then we carefully pinned the little guy down exposing its guts and connective tissue inward parts, we removed these parts, leaving the skin. The leech was put under the microscope and a segment was cut out to see the ganglia. Then we cut the sinus and used an electrode to locate a cell. A feather, probe and forceps were rubbed against the cell and the reaction (action potential) was measured. The three stimuli acted as light, medium, and strong stimuli. Lastly, we injected the fluorescent dye and viewed it under the UV light. With the UV light, the cell body, axons, and dendrites were visible.
The way that the cell reacted to the different stimuli demonstrated how there are different ways cells respond to levels of stimuli (light, medium, strong). The neurons can react differently because of their specific function or because of their environment. For example, neurons on your hand will react differently to neurons on your legs or face. Neuron classes are determined by their reaction to various stimuli.

Remote Controlling Life

This title may surprise you. Life is remote controlled only in science fiction! But sadly (or happily), you are mistaken. A scientist attached the motherboard of a remote controlled toy to a cockroach. He put the wires into the antennae of the cockroach and into its brain. So the Remote Controlled Cockroach was created. This can easily be seen as an ethical issue. Remote controlling life seems sort of wrong, but it doesn't seem so bad with an insect. But what about with a rabbit, a dog, or a human? Most people would immediately be repulsed at the idea of sticking a wire in someone's brain and sending electrical signals through them so that they can be controlled by a joystick. 

Man remote controlling another
person (Kind of looks like Mr. Gaume,
does it not?)

Before anyone goes rejecting or embracing an idea, we must think of the positive and negative aspects of such a thought. On the positive side, people that have been paralyzed by some unfortunate event could again walk. If this works, could the blind be coaxed to see again? Could the mute speak again? If an electrical signal can somehow bypass the damage inflicted upon the brain/ nerves during an accident, couldn't it stimulate a part that has been damaged, such as the visual cortex? Such ideas are fantastic if they did work, and were only used for ethical purposes? But what is ethicsAccording to Webster's Dictionary, ethics is "a set of moral principles". Most people would agree that certain things are right or wrong, and remote controlling a human being is one of those things. The negative side to this is as stated, the ethical implications. People controlling other people against their will is a frightening idea. The question is "who would decide who is remote controlled, who would have the ultimate power?". Power over life. In my opinion, this power shouldn't be designated to any human. 
In conclusion, this experiment was neat, and there will be a constant struggle over whether it is ethical. This could revolutionize science or maybe start a revolution. There is no clear cut answer and there will never be?

Three Questions! (November 9)

1. This week we finished the Muscular System in anatomy! All of the blogs, glogs, packets, and test are finally done! Such a relief! I also covered more about Integrals in Calculus and started reading Frankenstein in English.

Nervous System next week!

2. I have to admit I've learned a ton of stuff in anatomy while studying the muscular system. The physiology of a contraction is just amazing, and I think I've got origin and insertion down (even if all the thigh muscles seem to have the same ones). I also learned a lot in French this week. I'm getting much better at writing paragraphs.
3. Next week I need to finish and turn in my Macbeth essay. We're also starting the next system in anatomy, the nervous system I believe. I'm pretty excited about this one. There will undoubtedly be more glogs, blogs, and packets...again.

Three Questions! (November 2)

Orson Welles as Macbeth
circa 1948

Here's another installment of three questions! November 2nd edition. This is what I've done, learned, and hope to accomplish next week.
1. Lately I have worked on my muscular system packets and coloring plates.
2. This week I understood more of the muscular system microscopic anatomy after our class lecture/ discussion (more, please!). It's actually a really fascinating, yet cool process. In math, we started learning Integrals (whoo!), and in English I almost completed my essay on Macbeth. 
3.Next week I hope to finish the packets before the test and study for the Muscular System test. I will also do my glog on Fibromyalgia. Then I'll do some more studying and work on my online history class.

Skeletal Muscle!

Diagram showing all the -mysiums and the fascicle

Skeletal Muscle is awesome! It allows us to run, smile, and give high fives. It's composed to hundreds to thousands of muscle cells, connective tissue wrappings, and blood vessels and nerves. Each cell spans the length of the muscle! Take the Sartorius, a very long muscle in the thigh region. This muscle can be a couple feet long, which is pretty crazy because most people thing of cells as tiny things. How does such a large cell survive, you ask? They are extremely skinny, perfectly suited to reside in our skeletal muscle. The cells are multinucleate and are thin enough for nutrients to get in and waste to be excreted. The cells are in bundles called Fascicles. In between the cells, also called fibers is the Endomysium. Perimysium surrounds the bundles, and Epimysium holds it all together on the outer surface. These three layers are essential in skeletal muscle; this type of muscle goes through a lot, pulling on the bone all the time. The reinforcement keeps the muscle from tearing, and possibly tearing off the bone if enough force is applied.

Arnold doesn't know how much
effort it takes his body to flex! 

The main goals of the muscular system include movement, heat generation, stabilizing joints, and maintaining posture. None of these would be possible without contraction. Did you know only one third of our muscle cells contract at any one time? If they all contracted, it would be too much force to handle and the muscle could rip from the bone!  The smallest unit of contraction in skeletal muscle is the sarcomere. In the sarcomere are the two proteins that facilitate contraction, called myofilaments. The myofilaments are called Myosin (thick filaments) and Actin (thin filaments). During contraction, the Actin slides towards the center of the sarcomere, pulling the edges of sarcomere (Z Plate) and shortening the cell. When all the cells contract together, movement is produced! Since we know that skeletal muscle is voluntary, you tell your arms, legs, and hands to move to perform a certain function. This seems like a long process, here's how it goes. You decide you want to raise you arm, so your brain sends an electrical signal to the muscle. This signal starts a chain of chemical reaction and uses some ATP to attach the Myosin and Actin. The Actin slides, and your arm moves. Then more ATP is used to relax your arm. This whole process took longer to read than it took to actually happen! This long, specific series of impulses and reactions took place without much though in a fraction of a second! Pretty amazing if you ask me!

Three Questions! (October 26)

1. I have completed part of my coloring plates for the macroscopic anatomy of the Muscular System. I also took a quiz on the names in Anatomy. I also finished Chapter 4 in Calc. (with a hard test!), and took the ACT!

These two could potentially lift
the same amount of weight!

2. This week I learned all of the anterior/posterior muscle names! We also watched a VERY interesting video about muscles! There were examples of people who used their muscles to their full capacity in times of crisis. One of the examples was of a man who was hiking and had to lift a 1200 pound rock off his body! While doing this, all of his muscle cells contracted at one, lifting the rock, but tearing his muscles from the bone (painful!). It turns out we can all lift almost of a ton of weight, but we only use one third of our muscles capacity. This is because if we used more, we would use energy too quickly, overheating our body. 

3.This week I'm planning on learning the origin, insertion, and action of the muscles. I'm also going to keep working on the packets for the muscular system!

Literacy Glog

Man with Smallpox

Yes! The Demon in the Freezer is everything I hoped it'd be. Preston writes in such a way that you can't help but just to be engrossed in the story. He even makes jokes about the characters  he really makes them come alive. I've learned from the book what exactly smallpox does to you and how it came about. It is a graphic process that makes you really feel bad for those who had to go through it. It makes you really feel grateful for the people who worked so hard to create a vaccine for smallpox.Those scientists used many methods to keep the smallpox from spreading. When a case was reported, the doctors and scientists would vaccinate up to 30,000 people that lived around the case (that's A LOT of people!). I also learned that there was a threat of a biological weapon when President Bush was in power. The threat was from the Soviet Union, and the U.S. was informed of this by British Intelligence. The eradication, and even threat of a biological weapon most definitely had an impact on history and science. No longer was it a major feat for science, the smallpox eradication 1979 saved many from pain and suffering. The threat from the Soviet Union prepared the United States to handle a weapon that can kill invisibly. It's almost scary to think that a weapon like that could be around without being known about!! I'm learning a lot and can't wait to finish!

Three Questions! (October 19)

Newton!

1. Lately I have completed the Skeletal System section and test in anatomy, and discovered a band called Head of Femur. Also, I recently took the PSAT on Wednesday (whoo no more studying!)
2. This week I learned that you are born with the same amount of muscle cells that you have today, unless some have died. I also learned that we have a muscle called the Tensor Fasciae Latae in our leg! (cool name). In calculus, we now know how to use Newton's Method to find where a function crosses the y-axis without using a calculator!
3. This weekend and next week I plan to start the packets on origin/insertion and start memorizing the muscles for the quiz on Thursday. I also plan on doing Calc homework and reading more of Pride & Prejudice.

Skeletal & Integumentary Systems

Skin

Skeleton 

The Skeletal and Integumentary system both protect the body. The Skeletal system protects the organs and other body parts by forming cages around them, like in the skull and the rib cage. The Integumentary system protects the body by killing bacteria by skin secretions, and warding off UV radiation by darkening (producing more melanin). The skin also contains pain and pressure receptors that let the brain know when a homeostatic response needs to be issued to maintain proper function. The Integumentary system even protects the Skeletal system from superficial damage, and also help aesthetically! Who would want to see all their bones and muscles without a covering? No one! Instead we see a smooth, beautiful surface.  These two systems give shape to our bodies, as well as protection, as mentioned earlier and are closely connected.

The Demon in the Freezer

Smallpox Virus

For my literacy glog, I chose The Demon in the Freezer by Richard

Book Cover

Preston. After reading The Hot Zone last year, also by Preston, I heard that he wrote another book about smallpox. I wanted to read it, and it turns out to be on the reading list, a lucky coincidence. The book is about smallpox, its eradication in 1979 and the process that the medical professions went about to exterminate the disease. I can't imagine getting smallpox after reading what some people had to go through, pretty frightening stuff! Living in a time with no vaccines for viruses like smallpox would feel as if there was no hope. Preston discusses a lot of history, which I don't like much, but he makes it really interesting! He tells of only two stores of smallpox that were kept, but other nations have it, and they can easily set it loose as a biological weapon. This is an interesting yet frightening idea. Preston makes the history interesting, involving commentary from the individuals who actually put an end to the spread to the smallpox virus. He includes always intriguing observations, and I'm excited to learn what happens next.

Skin...Our Personal Bodyguard

Man enjoying the cooling benefits of sweat

Skin is pretty amazing. It is your largest organ and protects you from the outside environment. The skin is designed to protect you from mechanical, chemical and biological damage. The parts that make up the skin are perfectly suited to their jobs. First, the skin is made up of three layers: the Epidermis (outer layer), Dermis (middle layer), and Hypodermis (deepest layer). The Hypodermis isn't actually part of the skin, it just anchors it to the underlying organs, but for now we'll just include it. The outermost layer, the epidermis has an outermost layer of dead cells, so they can be sloughed off without damage to the underlying  layers. Pretty cool right? And even if the damage is deeper than the epidermis and enters the dermis, it's all good. The dermis is made of dense connective tissue, and strong substance designed to protect the organs underneath. Not only does the skin have these three layers, it also has hair and ducts that secrete substances that protect us. The hair increases the sensitivity of the skin, and allows tissue to regenerate in the hair follicles, where it wouldn't be able to regenerate somewhere else. Sebum and sweat are the substances secreted by the skin to protect it. Sebum keeps our skin and hair hydrated and creates an acid barrier that protects us from chemical and biological factors, like bacteria. The skin also regulates the temperature of our body. There are several ways for our body to cool down, including sweating and vasodilation (expansion of vessels). This expansion brings the blood closer to the surface, allowing heat to escape. Vasoconstriction (contraction of vessels) brings blood away from the surface preventing heat loss. Vasocontstriction, along with goosebumps keep the body warm and cozy. Another function of the skin is to protect the body from UV radiation. The skin has these things called melanocytes that produce melanin, which is partly responsible for skin color. Increased exposure to the sun generates more melanin, which darkens the color of the skin (a tan). The darker color actually acts as a barrier to block out some UV rays. So the skin will actually change to protect itself from harmful radiation. Skin is pretty amazing; I don't know what we would do without its protection.

A Tale of Two Tissues...Form Meets Function

Stratified Squamous Epithelial Tissue

Tissues are one of the most diverse structures in the human body. They can stretch, protect and filter  to fill the needs of the body. The diversifying element in tissues are their form. Different form, different function. For example, simple squamous tissue is a single layer of small cells that are used for absorption, secretion, and exchange of substances. Their small shape allows for quicker diffusion, like in the lungs where gases need to be exchanged efficiently. Stratified Squamous has a similar name but a remarkably different function. Stratified tissue has multiple layers and in this case is used where friction is often found. This way a layer can be removed and the body is not harmed. Stratified Squamous tissue makes up the skin, mouth, and esophagus. Imagine you get scraped by something, and you're down to the muscle? Not a pretty sight, and this is exactly why multiple layers are absolutely essential. These are both types of Epithelial Tissue. Other types include Connective, Muscle, and Nervous Tissue. Each of these three Tissue types has a radically different function, yet they are all tissues. 

Potatoes

Tissues are like potatoes- there are different functions for potatoes (mashed, baked,  or made into a  delicious salad), but in the end they are all potatoes. Getting back to tissues, there are even different shapes they can be. Long, short, or something in between. They can be stretchy, hard, and even pliable.As mentioned in the video, there are many very different functions of silk. It can be made into clothes, but can also filter and be woven into ropes. Concerning tissues, the point of having all these forms, and therefore functions is to create a diversity of capabilities, and support homeostasis. A single type of tissue cannot maintain homeostasis alone. Nervous tissue can sense stimuli and send a signal to muscles to expand or contract. The tissue on the skin (stratified squamous) keeps out foreign invaders and maintains internal temperature. This isn't just a tale of two tissues, it is a tale of many that work together to keep the body in tip top shape.

Megan...a Digital Native in her own right.

iPod

Being a digital native is an interesting concept, and being a part of the group known as 'digital natives' has a different meaning for everyone. In my opinion, people who grew up in the age of the internet, or who have immersed themselves in the world of technology are digital natives. Those in the latter group chose to join the digital bandwagon, but us who were born into it didn't have a choice. Or do any of us have a choice anymore? Society is already quite technologically advanced, and is heading more that way everyday. I fit into the first group. I have never known of anything but the internet, and didn't think it was revolutionary when it was created. All of my friends have cell phones and regularly use the internet, in fact they have become reliant on it. Although I am not the most technologically savvy person I have ever met, I do rely on e-mail and cell phones plenty.  Now small children have cell phones and are iPad experts. Social networking, online classes, and online bill pay have become normal when they weren't fifteen years ago. The internet is great, but what would happen if it one day went away? How would us digital natives fare in a world without technology?
