Humerus Bone, Lateral View

Description

Oriented in lateral projection, the humerus is highlighted along its full length from the rounded head and anatomical neck proximally to the lateral epicondyle and distal shaft. Superiorly, the humeral head sits medial to the greater tubercle as it approximates the glenoid cavity of the scapula, while the surgical neck marks the transition into the shaft. Midshaft, the deltoid tuberosity forms a coarse, lateral elevation for deltoid insertion, and the bone’s relationship to the scapula and clavicle frames the shoulder girdle in anatomical position. Key lateral landmarks read cleanly. Lateral humeral anatomy matters when you need to correlate surface landmarks with function and injury patterns. The deltoid tuberosity helps orient the rotational alignment of the shaft and is a practical teaching point for deltoid leverage in abduction, while the surgical neck is the common fracture site where the axillary nerve and posterior circumflex humeral artery are at risk. This projection also supports explanations of glenohumeral congruency and why displaced proximal humerus fractures can compromise shoulder mechanics even when the glenoid and acromioclavicular region appear intact. Use this artwork in gross anatomy and kinesiology modules covering the brachium, in orthopedic texts discussing proximal humerus fractures and axillary nerve palsy, or in patient education materials that need a clear lateral reference of the shoulder joint and upper arm bone. It also suits radiology primers as a schematic companion to AP and scapular Y views when introducing bony landmarks before imaging. Anatomical accuracy verified by SciePro's Medical Advisory Board.
