Lecture 6c: skeletal muscles muscles of the pectoral girdle and upper limbs. Objectives: identify muscular compartments, pe(cid:272)toral (cid:858)or shoulder(cid:859) girdle, ar(cid:373) (cid:858)or (cid:271)ra(cid:272)hiu(cid:373)(cid:859) form elbow to the shoulder, forear(cid:373) (cid:858)or a(cid:374)te-(cid:271)ra(cid:272)hiu(cid:373)(cid:859) from the elbow to the wrist. Muscular function- large muscle has multiple function we can move certain fibers to do certain movement: can cause opposite movement. Certain region off the spinal cord that come together and forms a nerve web: cervical plexus has the phrenic nerve, lumbar and sciatic plexus the femoral nerve comes off it. Allows for constant innervation for gives multiple path for muscles to. Example the brain has multiple that can still give the brain blood communicate with the sympathetic nerve. Brachial plexus goes to the brachial region in terms of injury and sciatic. The brachial plexus emerges at five different levels; c5, c6, c7, c8, and t1. Prefixed or post fixed formations in some cases involve c4 or t2,
