Muscular System Reflection


In this unit, we covered the muscular system which consists of all the muscles in the body and how our muscles move by contracting and relaxing. The main functions of the muscular system are the movement of the bones and fluids such as blood, maintaining body position, and stabilizing joints. Muscles are classified as prime movers, antagonists, synergists, and fixators. These classifications differentiate how the muscle moves and if they contract or relax. Muscle contractions include many bundles of muscle fibers. Each muscle fiber contains myofibrils and each myofibril is lined up with sarcomere. Muscle contractions are a complicated process that starts with sending an impulse to the muscle. Then a multitude chemicals such as Ca 2+, ATP, and Phosphate are released and the myosin binds in a pulling action which makes the muscle contract.

I think that this unit was extremely in depth and we covered how muscle moves down to every detail. As a result, there isn't anything I have questions on. However, I do feel like the way the muscle contracts is a little complicated. I was wondering if there could maybe be an easier way for muscles to move. I couldn't really think of a more effective way for muscles to move, but it was something interesting for me to think about. 

I think I was able to learn a lot and grow a lot throughout the last two units, the muscular system and the skeletal system. I really liked these units, because it was really relatable to me since I had a lot of injuries that consisted of broken bones and joints. I also always wanted to know how a muscle was able to move since it is such a important function in our daily lives, but it's always overlooked and taken for granted. I was glad to finally able to understand how muscles work.
