Description
The flexor pollicis brevis muscle is a small, flat muscle located in the hand. It extends from the flexor retinaculum and the metacarpal bones to the base of the proximal phalanx of the thumb.
The main function of the flexor pollicis brevis muscle is to flex the thumb at the metacarpophalangeal and interphalangeal joints. It also helps to adduct the thumb towards the hand.
The flexor pollicis brevis muscle is commonly used in activities that require flexion and adduction of the thumb, such as gripping objects or pinching. It is also used in activities that require stability of the thumb, such as playing a musical instrument or typing.
