Which of the following is the motor nerve innervating most thenar muscles?
A. Ulnar
B. Median
C. Radial
D. Axillary
E. Musculocutaneous

Intially, I thought the thumb is innervated by the radial nerve...but after some investigating...I think the radial nerve is cutaneous innervation...the Median nerve does motor innervation to the opponens, abductor, and flexor..

Is the answer B. Median?

I believe it is median nerve
