The Flexor Digiti Minimi is a small muscle located in the hand. It is responsible for flexing the little finger, or the fifth digit, at the metacarpophalangeal joint. This muscle originates from the hamate bone and the flexor retinaculum, and it inserts into the base of the proximal phalanx of the little finger. This muscle is part of the intrinsic muscles of the hand, which are crucial for fine motor skills and grip. The Flexor Digiti Minimi works in coordination with other muscles, such as the Abductor Digiti Minimi, to enable precise movements of the little finger, enhancing overall hand function.
