Volar aspect of right hand
Nerve supply to third and fourth lumbrical muscles and opponens digiti quinti muscle
The flexor tendons and lumbrical muscles have been retracted distally. The opponens digiti quinti muscle has been dissected.
1 . Sheath of common tendon of flexor muscles (opened, tendons and lumbrical muscles reflected distally)
2 . Lumbrical muscle III
3 . Lumbrical muscle IV
4 . Flexor digitorum profundus muscle (tendon to fifth finger)
5 . Lumbrical muscle I (cut off)
6 . Adductor pollicis muscle
7 . Flexor pollicis brevis muscle (deep head)
8 . Metacarpotrapezial joint capsule
9 . Transverse carpal ligament
10 . Carpal tunnel
11 . Branches of of ulnar nerve
12 . Ulnar artery
13 . Muscular branch ulnar artery (in position usually occupied by deep anterior branch ulnar artery)
14 . Deep branch of ulnar nerve
15 . Flexor and abductor digiti minimi muscles (area of origin)
16 . Muscular branch of ulnar nerve (to opponens digiti minimi muscle)
17 . Opponens digiti minimi muscle
18 . Deep anterior branch ulnar artery (aberrant origin more distal than usual)
19 . Anterior interosseous fascia
20 . Muscular branch of ulnar nerve (to Iumbrical muscle III)
21 . Proper palmar digital artery
22 . Muscular branch of ulnar nerve (to lumbrical muscle IV)
23 . Flexor and abductor digiti minimi muscles (area of insertion)
24 . Tendon of digital sheath V (opened)
