The thenar eminence is the muscular bulge on the radial side of the palm of the hand due to the thenar muscles. Two are innervated by median nerve, and flexor pollicis brevis is innervated by the ulnar nerve. Together the muscle group primarily acts to oppose the thumb. The three muscles are:

The adductor pollicis muscle is not one of the thenar muscles and - like flexor pollicis brevis muscle - is innervated by the ulnar nerve.

The three muscles of the thenar eminence with adductor pollicis form the short muscles of the thumb, part of the intrinsic muscles of the hand group.
