Document Summary
Acrominal end: flat end, where clavicle art w acromion of scapula. Posterior surface: spine w acromion and acromioclavicular joint where clavicle and scapula join. Glenoid fossa: socket joins w head of humerus to form shoulder bone, on lateral side. Surgical neck: where body starts, most likely to fracture. Proximal end: greater tubercle which is lateral, deltoid tuberosity= deltoid attachment lesser tubercle which is medial + anterior. ) and lateral epicondyle s (radial collateral lig attachment trochlea: medial, art w bones of forearm during flex/extensi on capitulum: lateral, art w bones during flex/extension, anterior only. Coronoid fossa: anterior, where ulna bone fits during flexion. Olecranon fossa: posterior, where ulna fits curing extension. Trochlear notch: made of olecranon and coronoid process, holds trochlea of distal humerus= forms hinge joint. Radial notch: art w articular surface of head of radius. Styloid process: attachment to ulnar collateral ligament of wrist. 14, proximal, middle and distal for all except thumb which dn have middle.
