Medial Border of the Forearm, Anterior View

Description

Oriented in anatomical position, the antebrachium is presented from an anterior perspective with attention drawn to the medial border where the ulna defines the ulnar (medial) margin of the forearm. Medial to lateral, the viewer can infer the subcutaneous ulnar shaft running toward the ulnar styloid, while the radius lies more lateral and contributes less to the medial contour in this view. Proximally, the border aligns toward the region of the medial epicondyle of the humerus, and distally it approaches the ulnar side of the wrist, where the flexor carpi ulnaris tendon and pisiform sit superficially. Medial forearm anatomy matters because it frames several high-yield neurovascular and surface landmarks used in daily clinical work: the ulnar nerve courses posterior to the medial epicondyle before entering the forearm between heads of flexor carpi ulnaris, and the ulnar artery travels deep to that muscle as it descends toward Guyon’s canal at the wrist. Know this corridor. Symptoms from cubital tunnel syndrome, traction injuries around the elbow, or iatrogenic irritation from medial elbow procedures are often mapped by learners back to this medial border. For vascular access, the basilic vein typically ascends along the medial forearm and arm, making the ulnar side a common teaching target for venipuncture and for discussing the nearby medial antebrachial cutaneous nerve that can be inadvertently injured. Faculty can place this figure directly into upper limb gross anatomy labs, surface anatomy workshops, and musculoskeletal examination teaching to cue ulnar-sided palpation, landmarking, and dermatomal or peripheral nerve sensory testing. It also fits well in medical publishing for chapters on forearm compartments, cubital tunnel release approaches, and clinical correlations of ulnar-sided wrist pain.
