Volar aspect of right hand
Thenar and hypothenar muscles, general view
A superficial stratum (3) of the abductor pollicis brevis has been detached from its origin and reflected distally. The deeper part of this muscle (8), which is partially fused with the opponens pollicis (10), remains in place.
1 . Proper palmar digital nerves of median nerve
2 . Dorsal digital nerve of radial nerve
3 . Abductor pollicis brevis muscle (superficial part, reflected from origin)
4 . Position of first metacarpophalangeal joint
5 . Muscular branch of median nerve (to abductor pollicis brevis muscle)
6 . Lumbrical muscle
7 . Anterior common digital artery (to thumb and index finger)
8 . Abductor pollicis brevis muscle (deeper part)
9 . Flexor pollicis brevis muscle (superficial head)
10 . Opponens pollicis muscle
11 . Muscular branch of median nerve (recurrent branch source of nerve labeled at 5)
12 . Remnant of palmar aponeurosis
13 . Abductor pollicis longus muscle
14 . Transverse carpal ligament
15 . Superficial anterior branch radial artery
16 . Flexor carpi radialis muscle (tendon of insertion)
17 . Anterior carpal ligament
18 . Ulnar artery
19 . Ulnar nerve
20 . Opponens digiti minimi muscle
21 . Left pointer: Sheath of common tendon of flexor muscles (inflated with air) Right pointer: Lobule of fat
22 . Left pointer: Median artery Right pointers: Branches of median nerve
23 . Anastomotic branch of median nerve with ulnar nerve
24 . Flexor digiti minimi muscle
25 . Lumbrical muscles II-III
26 . Tendon of digital sheath IV
27 . Anterior common digital artery
28 . Abductor digiti minimi muscle
29 . Ligament of digital sheath
30 . Anterior proper digital arteries
