Document Summary

Bone: humerus, shaft (with bicipital groove, head, neck & tubercles, condyles & epidcondyles, medial = trochlea, lateral = capitulum, coranoid fossa (anterior, olecranon fossa (posterior) Arteries: brachial artery, anteromedial in upper arm, moves laterally and anteriorly at elbow to form ulnar and radial art, profunda brachii artery. Muscles of the anterior compartment (musculocutaneous nerve: biceps brachii, o = supraglenoid tubercle, coracoid. I = radial tuberosity, forearm fascia: f = forearm flexion at elbow, supination (supination magnus), assists shoulder flexion, brachialis, o = anterior surface of humerus, f = flexion of forearm at elbow. I = coranoid of ulna: coracobrachialis, f = assists flexion of arm at shoulder. Posterior compartment muscles (innervated by radial nerve: triceps brachii, o = infraglenoid tubercle, upper lateral & lower medial halves of the posterior shaft of humerus. I = olecranon of ulna: f = extension of forearm at elbow, anconeus (posterior forearm, f = assists triceps brachii.
