Document Summary

Pectoralis major: prime mover of arm flexion rotates arm medially, abducts arm. Latissimus dorsi: broad, flat back muscle; prime mover of arm extension rotates arm at shoulder, adducts arm. Deltoid: thick, rounded, prime mover of arm abduction-lateral & medial rotations, flexion/extensions-some fiber. Biceps brachii: front, flexes elbow joint + supinates forearm weak flexor of arm at shoulder. Brachialis: deep inserted to biceps brachii - powerful major forearm flexor. Brachioradialis: superficial, far apart from humerus & forearm, helper in forearm. Muscles of the forearm: movements of the wrist, hand & Pronator teres: pronates forearm, weak flexor of elbow. Flexor carpi ulnaris: powerful flexor of wrist adducts hand. Flexor digitorum superficialis: 2 headed deeper, flexes wrist. Extensor digitorum: prime mover of finger extension, extends wrist. Iliopsoas: 2 muscles - prime mover of hip flexion. Sartorius: longest muscle flexes & laterally rotates thigh weak knee flexor. Adductors: all adduct, flex, medially rotate thigh powerful flexor of wrist, abducts hand flexion.
