Recurrent branch of the median nerve

The recurrent branch of the median nerve (which has also been called "the million dollar nerve") is the branch of the median nerve which supplies the thenar muscles. It is also occasionally referred to as the thenar branch, or the thenar muscular branch, of the median nerve. In the thenar eminence it provides motor innervation to opponens pollicis, abductor pollicis brevis and flexor pollicis brevis. An earlier branch of the median nerve also supplies the lumbricals 1 & 2. All other intrinsic muscles of the hand are receive their motor innervation from branches of the ulnar nerve.

It usually passes distal to the transverse carpal ligament.

It ends in the opponens pollicis.
