Anatomy and function of the thenar muscles

Salil Gupta et al. Hand Clin. 2012 Feb.

Abstract

The four thenar muscles make up the intrinsic muscles of the thumb. They include the abductor pollicis, adductor pollicis, opponens pollicis, and flexor pollicis brevis. Thumb motion is facilitated through the coordination of these intrinsic muscles. The thumb musculature dynamically allows for precision pinching ad power gripping.
