Document Summary

The muscles overlay the skeleton and provide the means to move it. Each muscle produces a motion when it creates tension and tries to shorten (it will always try to shorten but if there are external force placed upon it, it may lengthen instead. Its attachments and orientation determine what moves and how. Muscles move from nervous signals from the brain (why we classify it as the neuromuscular system) Muscles are on the outside of bone. There are different shapes and wrappings of muscles, different alignment of fibres and different sizes of tendon attachments at either end (these features dictate how the muscle will behave) All skeletal muscle have at least 2 attachments one being on a different bone so that muscle crosses at least one articulation. The muscle groups are named after the movement that they cause but that does not mean that every time that movement occurs that the muscle group is causing it.
