(ON THE RIGHT SIDE ONLY) Identify the superficial nerves, arteries and muscles of the hand. (G 2.74A;N 447;Gl 28.44A)

1. Identify the transverse carpal ligament (G 2.74A;N 453;Gl 28.42B) This is the deep portion of the flexor retinaculum. It is immediately anterior to the carpal tunnel.
2. Identify the superficial palmar arterial arch and the common and proper digital arteries. Attempt to identify the anastomosis between the superficial palmar arterial arch and the superficial palmar branch of the radial artery.
3. Identify the ulnar nerve adjacent to the pisiform bone. (G 2.74A;N 453;Gl 28.44A) Identify the common and proper digital nerves (branches of the ulnar nerve).
4. Identify the three hypothenar ( abductor digiti minimi, flexor digiti minimi brevis and opponens digiti minimi) muscles. (G 2.74B;N 449;Gl 27.25) The opponens digiti minimi muscle is deep to the abductor digiti minimi muscle (attached to the shaft of the 5th metacarpal).
5. Identify the four lumbrical muscles. (G 2.74B;N 449;Gl 27.27A) Trace the 1st lumbrical to its distal attachment to the extensor expansion. (G 2.87B;N 451;Gl 27.23)
6. Identify the branches of the median nerve ( common and proper digital, and recurrent) immediately distal to the transverse carpal ligament. (G 2.74B;N 453;Gl 28.44A)
7. Identify the three thenar muscles ( flexor pollicis brevis, abductor pollicis brevis and opponens pollicis muscles (this muscle group is identified incorrectly in the VH Dissector). (G 2.74A;N 452;Gl 27.18) Expose the opponens pollicis muscle by reflecting the abductor pollicis brevis muscle.
8. Trace the tendon of the flexor pollicis longus muscle to its attachment to the base of the distal phalanx of the thumb. (G 2.77;N 452;Gl 27.18D) Identify its fibrous digital sheath.
9. On the second digit, trace the tendons of the flexor digitorum superficialis and profundus muscles to their distal attachments (middle phalanx and base of distal phalanx). (G 2.78;N 451;Gl 27.18D)
