The Muscular System

This are all of the things that I've learned in the topic muscular system. It was really a huge topic that includes many things. The three main types of muscle are skeletal, smooth and cardiac. The skeletal muscle is striated or striped voluntary muscle that allows movement, stabilizes joints and helps maintain body temperature. Smooth muscle is a nonstriated involuntary muscle that is found in the organs of the body and linings of vessel. The cardiac muscle is also an involuntary muscle but a striated one found only in the heart. I've learned that all movement is a result of contraction of primary movers and relaxation of opposing muscles. muscles are usually attached to the bones by tendons. Large muscles are consist of many single muscle fiber comprised of myofibrils. Muscles contract as the actin and myosin protein filaments. There are also many common diseases and conditions of the muscles.

This topic serves as an interesting one. However, it could have been more effective if we had other activities that are interesting and not boring so that we could understand it further. All in all, the reporter has come up with accomplishing her task.
