Shoulder, Anterior View

Description

Anteriorly, the clavicle runs horizontally from the acromion toward the manubrium, forming the superior boundary of the pectoral girdle while the scapula sits posterolateral to the thoracic wall with its glenoid cavity facing laterally. Inferior to the acromion, the humeral head articulates with the glenoid at the glenohumeral joint, and the surgical neck continues distally into the humeral shaft. At the lateral end of the clavicle, the acromioclavicular joint is visible where the clavicle meets the acromion, a key bony landmark for orienting the coracoid process and the anterior scapular margin. Bone relationships are clear. For teaching and clinical correlation, this orientation maps directly to the usual surface anatomy you palpate, clavicle, acromion, and the anterior contour of the humeral head, and it frames the mechanics of anterior shoulder instability when the humeral head translates anteroinferiorly relative to the glenoid rim. The acromioclavicular joint line and distal clavicle also matter in grading AC separation after a fall on the adducted shoulder and in planning distal clavicle excision, while the glenohumeral relationship provides context for Hill-Sachs and Bankart lesion discussions even when the labrum is not shown. Use this illustration in gross anatomy labs and musculoskeletal modules to anchor bony landmarks before adding rotator cuff tendons and capsuloligamentous structures, and in orthopaedic or sports medicine teaching files that introduce shoulder dislocation patterns, AC joint injury, and approach planning for the deltopectoral interval. It also suits medical publishing layouts that need a clean anterior reference for labeling the clavicle, scapula, humerus, and primary shoulder joints.
