If a muscle crosses the metacarpophalangeal and interphalangeal joints of fingers two through five on the dorsal (posterior)side with a vertical orientation to its fibers,what will its eccentric function most likely be?

Question

Quizplus · Accepted Answer

Muscles on the dorsal side of the hand that cross the metacarpophalangeal and interphalangeal joints would act to extend the fingers at these joints. Therefore, their eccentric function, which involves controlling or slowing down the opposite movement, would be to restrain or slow down flexion of the fingers at these joints.
