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.

- Dorsal digital nerve of radial nerve
- Abductor pollicis brevis muscle (superficial part, reflected from origin)
- Position of first metacarpophalangeal joint
- Muscular branch of median nerve (to abductor pollicis brevis muscle)
- Lumbrical muscle
- Anterior common digital artery (to thumb and index finger)
- Abductor pollicis brevis muscle (deeper part)
- Flexor pollicis brevis muscle (superficial head)
- Opponens pollicis muscle
- Muscular branch of median nerve (recurrent branch source of nerve labeled at 5)
