Document Summary
Not responsible for origin and insertions (she"ll tell you though) Origin or head muscle: end of muscle attached to more stationary of two bones. Muscles attach to at least two bones across a joint. The bone that is more stationary is called the origin. Insertion: end of muscle attached to bone with greatest muscle. Belly: largest part of the muscle between origin and insertion. Sheet like tendons that connect flat muscles to broad regions of bone. Agonist: muscle, that when it contracts, it causes an action. Antagonist: a muscle working in opposition to agonist. Synergists: muscles that work together to cause a movement. Prime mover: plays larger role in accomplishing movement(involved in the movement) Fixators (helper muscles): stabilizes joints crossed by the prime mover, prevent movement of the origin of the prime mover. Size: maximus (largest of group) , minimus (smallest of group), longus, brevis (shortest) Muscles that run from spinous processes to the occipital bone or mastoid process.
