Document Summary

Functions of skeletal muscles: produce movement, maintain posture, stabilize joints, generate heat - shivering. Gross anatomy of skeletal muscle: connective tissue sheets, attachments, nerve and blood supply. Muscle attachments: most muscles, span joints, are attached to bones in at least 2 places, origin and insertion, when the muscles contract (shorten) the insertion point is pulled towards the point of origin* Nerve and blood supply: a motor unit consists of motor neuron axon and all of the muscle bers it innervates (activation of the muscles) Structural and functional organizational levels of skeletal muscle. The axial muscle: stabilizes and positions the head, neck and trunk, can be divided into 4 broad groups based on location and/or function. Muscles of the head: two groups, muscles of facial expression, muscles of mastication and tongue movement. Face/facial expression: insert into skin or other muscles, not bones, are all innervated by the facial nerve.
