Which muscles of the hand are supplied by the median nerve?

Remember MEAT LOAF:
Median nerves supplies: lateral two lumbricals, opponens pollicis, abductor pollicis BREVIS and flexor pollicis BREVIS.

2

Which intrinsic muscles of the hand are supplied by the ulnar nerve?

Medial two lumbricals, hypothenar muscles (opponens digiti minimi, abductor digit mini and flexor digit mini BREVIS), dorsal and palmar interossei, adductor pollicis and palmaris brevis.

3

36

Which nerve innervates the plantar of the foot?

The tibial nerve: its branches (lateral and medial plantar) supply the whole of the plantar muscles of the foot.
