The three muscles that make up the thenar group are the abductor pollicis brevis, flexor pollicis brevis, and the opponents pollicis.
Abductor Pollicis Brevis, the main muscle that moves then thumb.
Flexor Pollicis Brevis lies next to the abductor, and it flexes the thumb at the metacarpophalangeal joint as well as the flexing and rotation of the first metacarpal bone where the metacarpal bone of the thumb joins the carpal bones of the wrist, the carpometacarpal joint.
Just like the abductor pollicis brevis, the opponens pollicis originates at the flexor retinaculum of the hand, and the tubercle of the trapezium, passing downward and laterally.
The three muscles that make up the hypothenar group are the opponens digiti minimi, flexor digiti minimi brevis and the abductor digiti minimi.
