pronation of forearm
assists triceps during forearm extension - 33anconeus innervationradial nerve
- 34median nerve suppliesflexor muscles on radial side of forearm
does not supply muscles in arm - 35median nerve travels withbrachial artery
lateral-upper half
medial-lower half - 36ulnar nerve suppliesflexor muscles on ulnar side of forearm
- 37ulnar nerve tracemedial to brachial artery
runs with superior ulnar collateral artery
pierces medial intermuscular septum
enters posterior compartment of brachium
passes around medial epicondyle
passes into forearm between flexor carpi ulnaris muscle heads - 38Radial nerve suppliesextensor muscles in posterior compartmen of brachium and wrist and hand and brachioradialis muscle
- 39radial nerve accompanied bydeep brachial artery
spirals around posterior surface of humerus in radial groove - 40Radial nerve passes into forearm bybetween brachialis muscle medially and brachioradialis muscle laterally
- 41radial nerve divides intosuperficial and deep branches near lateral epicondyle
- 42Musculocutaneus nerve innervatesmuscles of anterior brachial compartment
