Document Summary

Lecture 26: upper extremities iii muscles of the forearm: anterior compartment. Review the bones of the arm, forearm, and hand. Describe the 9 muscles of the anterior compartment of the forearm. Which 3 do not cross the wrist joint: superficial: pronator teres, flex. Digitorum superficialis: deep: flexor digitorum profundus, flexor pollicis longus, pronator quad. Describe the nervous innervation (muscular and cutaneous) of the forearm. Intertubercular sulcus sulcus in between lesser and greater tubercle. Greater tubercle more lateral; lesser tubercle more medial. Medial epicondyle bump on the medial side; above trochlea: medial supracondylar ridge ridge above medial epicondyle. Lateral epicondyle - bump on the lateral side; above capitulum: lateral supracondylar ridge ridge above lateral epicondyle. Coronoid fossa & radial fossa present on the anterior view. Olecranon fossa present on the posterior view. Radius is more lateral, and ulna is (cid:373)ore (cid:373)edial (cid:894)(cid:272)loser to (cid:862)u(cid:863)/(cid:455)ou(cid:895) Both distal & proximal radioulnar joint allow for pronation & supination.
