Median and ulnar nerve

Superficial flexor, medial surface of the ulna, the medial border of the radius, and the deep fascia of the forearm.

Lateral digital extensor - thoracic

Fourth and fifth digits. Radial nerve The lateral tuberosity of the radius, the shaft of the ulna, and the lateral ligament of the elbow joint.
