Document Summary

Objectives muscles of the forearm: anterior compartment: review bones of arm, forearm, hand, describe the 9 muscles of the anterior compartment of the forearm. Which 3 don"t cross the wrist joint: superficial: pronator teres, flex. Carpi radialis, palmaris longus, flexor carpi ulnaris: middle: flexor digitorum superficialis, deep: flexor digitorum profundus, flexor pollicis longus, pronator quad, describe the nervous innervation (muscular and cutaneous) of the forearm. Muscles of the anterior (flexor/pronator) compartment of the arm. Superficial (common flexor origin, most innervated by median nerve): pronator teres, flexor carpi radialis, palmaris longus, flexor carpi ulnaris. Deep: flexor digitorum profundus, flexor pollicis longus, pronator quadratus. 4 major muscles emerge from the common flexor origin (medial epicondyle of the humerus): pronator teres, flexor carpi radialis, palmaris longus, flexor carpi ulnaris. Brachioradialis an oddity receives innervation from the. Radial nerve and only the lateral is innervated by the.
