Arm compartments: anterior, flexors, innervated by musculocutaneous nerve, muscles. Brachial vein: posterior, extensors, innervated by radial nerve, muscles. Anconeus: separated by intermuscular septums, medial and lateral. Biceps brachii: pa, long head, short head: Radial tuberosity and fascia of forearm via bicipital aponeurosis (lacertus. Fibrosus: n: musculocutaneous nerve (c5-c7, a: flex arm/elbow (long head, supinate and bend elbow, at 90 of flexion. Biceps brachii will be a flexor: long head helps prevent anterior and inferior translation of humeral head. Explains why some people who have a very rounded shoulder, and their. Humerus is trying to move anteriorly, that their long head biceps brachii. Tendon becomes inflamed: transverse humeral ligament: holds biceps brachii in place near head of humerus. If bursa was already inflamed, pronation of arm could be painful. Brachialis: pa, da, n: musculocutaneous nerve (c5-c6, a: flex forearm (best in any position)
