Fig. (1) Superficial dissection of the right hand showing the tendon of palmaris longus (1) located lateral to the median nerve (2). An accessory head (3) of the abductor digiti minim (ADM, 4) has an aponeurotic origin from the medial border of the tendon of the palmaris longus (1). The accessory head is seen crossing the ulnar artery and nerve just above the pisiform bone (5). The superficial division of the ulnar nerve (6) comes to the surface lateral to the accessory head of the ADM and provides innervation to the palmaris brevis (7). Tendon of flexor carpi ulnaris (8); superficial palmar arch (9).
