Document Summary
The brachium is divided anterior/posterior by the medial/lateral intermuscular septum. Anterior compartment contains biceps brachii, brachialis, coracobrachialis. Posterior compartment contains triceps brachii, and anconeus (not important to focus on for lecture final) The antebrachium is divided by the anterior/posterior intermuscular septum and the interosseous membrane. Anterior compartment is supplied by the median nerve with the exceptions of the 5th and half of the fourth digit being innervated by the ulnar nerve and contains. Posterior compartment is supplied by the radial nerve and includes. Synergist in forearm supination, elbow flexion, shoulder flexion. While the long head is a biarticular muscle which also aids in shoulder flexion the overall group is uniarticular and therefore considered an agonist in elbow flexion. Agonist in radial deviation and wrist flexion. Agonist in wrist flexion and ulnar deviation. Agonist in radial deviation and wrist extension. Agonist in wrist extension and ulnar deviation.
