30
course of median nerve
travels with brachial artery upper arm = lateral to art lower arm = medial to art crosses cubital fossa superficially
31
crossing of the cubital fossa
median nerve and brachial artery cross superficially deep to/covered by the bicipital aponeurosis
32
radial nerve supply

38
branches of radial nerve in distal arm
branches to: brachioradialis and extensor carpi radialis longus articular branches at elbow joint
39
ulnar nerve supply
supplies flexors on the ulnar side of forearm
40
ulnar nerve course
``` medial to brachial a runs w/ superior ulnar collateral art pierces medial septum enters post compartment passes superficial to medial epicondyle enters forearm ```
41
ulnar nerve insertion into forearm
between two heads of flexor carpi ulnaris
42
