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!
