Document Summary
Interosseous arteries: anterior interosseous artery supplies deep anterior muscles and small perforating branches through interosseous membrane to reach extensors, posterior interosseous artery supplies posterior muscles extensor muscles of. Branches off from common interosseous artery just before the membrane starts. Pathway of median nerve: c6, c7, c8, t1, runs anterior to brachial artery on medial side of humerus, enters antecubital fossa medial to biceps tendon. In forearm when it is proximal to interosseous membrane gives off a small anterior. Intrinsics and skin on the radial palmar surfaces. Initially follows beside median nerve- along medial humerus: c8 + t1, travels posteriorly to brachial artery, when it reaches the epicondyles takes a posterior path to between the medial. Epicondyle and olecranon posterioly cubital tunnel: then travels on medial forearm, before entering the ulnar side of the wrist, supplies skin of 4th and 5th digits (ant and post) + flexor carpi ulnaris and some of. Flexor digitorum profundus + intrinsic mm of hand.
