Male Arm, Posterior View

Description

Posterior surface anatomy of the male brachium is presented from the shoulder girdle to the elbow, with the triceps brachii forming the dominant contour along the posterior arm and tapering distally to its common tendon at the olecranon. The deltoid cap sits superolaterally at the shoulder, while the posterior axillary fold is suggested by the inferior margin of latissimus dorsi and teres major, framing the proximal medial arm. Distally, the olecranon and the medial and lateral epicondyles create the palpable bony triangle of the elbow, with the forearm (antebrachium) beginning inferior to the elbow crease and the dorsal forearm mass tracking along the ulna. Palpable landmarks matter. The posterior arm and elbow are examined constantly for triceps tendon integrity, olecranon bursitis, and distal humerus fractures, and this view helps anchor where swelling or ecchymosis sits relative to the olecranon and epicondyles. Clinically, it also supports safe orientation for procedures performed near the posterior elbow, where superficial landmarks guide needle placement and help avoid the ulnar nerve as it passes posterior to the medial epicondyle. Use this artwork in gross anatomy and surface anatomy teaching for upper limb, in physical exam manuals illustrating inspection and palpation points, or in orthopedics and sports medicine content discussing posterior elbow pain and triceps injury patterns.
