Quizplus · Accepted Answer

The flexor carpi ulnaris, when acting eccentrically, helps to control or slow down the movement of extension at the wrist joint. Eccentric muscle actions occur when a muscle lengthens under tension, often to decelerate a body part or resist gravity. In this case, the flexor carpi ulnaris would lengthen while controlling the speed of hand extension, preventing it from happening too quickly or forcefully.
