Structure and Location of the Female Humerus

Description

Centered on an adult female axial and appendicular skeleton, the paired humeri are emphasized in blue from the glenohumeral region to the elbow, lying lateral to the thoracic cage and inferior to the clavicles and acromia. Proximally, each humeral head faces medially toward the glenoid cavity of the scapula, with the greater tubercle positioned lateral to the intertubercular (bicipital) groove. Distally, the shaft widens into the medial and lateral epicondyles, aligning with the trochlea and capitulum at the elbow where the ulna sits medially and the radius laterally in anatomical position. Highlighting the humerus in the context of the shoulder girdle and proximal forearm makes fracture patterns and neurovascular risk easy to teach. Surgical neck fractures threaten the axillary nerve and posterior circumflex humeral artery, while midshaft fractures classically endanger the radial nerve in the spiral groove and present with wrist drop. The distal humerus landmarks also matter in supracondylar fractures, where the brachial artery and median nerve are at risk and elbow alignment lines become key teaching points. Use this plate for gross anatomy and osteology modules covering the brachium, for orthopedic teaching on proximal humerus fractures and humeral shaft fixation, or for patient education materials explaining why shoulder pain can coexist with distal neurovascular symptoms. It also suits exam preparation images that demand rapid orientation of the humerus relative to the clavicle, scapula, radius, and ulna.
