Muscles of the hand
- Three thenar muscles produce the thenar eminence and move the thumb
- Innervated by the recurrent branch of the median nerve (motor branch of median nerve distal to carpal tunnel)
- Thenar muscles are chiefly responsible for opposition of the thumb (flexion and medial rotation of the thumb when grasping or touching the fingers)
- These muscles are assisted in this action by the adductor pollicis and flexor pollicis longus
