bones and muscles
List the major bones of the body and at least one muscle that attaches to each (minimum of fifteen).

1. Skull - The occipitofrontalis is also known as the epicranius covers the top of skull.
2. Clavicle - Sternocleidomastoid Pectoralis Major Trapezius
3. Sternum - Sternocleidomastoid pectoralis major rectus abdominis attach here
4. Vertebral column
5. Ulna - The thumb extensors attach the ulna. The flexor and brachialis muscles attach here as well. ...

Solution Summary

Our body is supported by an internal skeletons comprised of many bones and muscles. These bones and muscles made up the skeletal systems that support our shape, movement, and everyday functions.
