Quizplus · Accepted Answer

The lumbrical muscles are the intrinsic muscles of the hand that flex the metacarpophalangeal joints and produce extension at the proximal and distal interphalangeal joints. They are responsible for the fine motor control of the fingers and play a critical role in grasp and manipulation. The other muscles listed may have other functions in the hand, but do not specifically perform these movements.
