Anatomy of an adult female corpse left upper limb, see palmaris longus absent. The distal 1/3 of the forearm from the ulnar side to the radial side of the shallow structure followed by the ulnar flexor tendon, superficial flexor tendon, median nerve, radial flexor carpal flexor tendon, tendon flexor. After passing through the anterior pronator of the pronator, the medial nerve was moved distally in subcutaneous fat tissue between the tendon of the superficial flexor tendon and the flexor carpi ulnaris at a distance of 5 cm from the upper edge of the transverse carpal ligament. Its distal more round, wide diameter of about 3.5mm; distal flattened, about 6mm wide. The median nerve at the upper edge of the transverse carpal ligament, wrist flexor carpi radialis 0.3cm, flexor flexor tendon 0.2cm. Center God
