Which are eccentric functions of the flexor digitorum superficialis?

Question

Quizplus · Accepted Answer

The flexor digitorum superficialis muscle primarily flexes the fingers (two through five) at the metacarpophalangeal and proximal interphalangeal joints. In an eccentric contraction, where the muscle lengthens under tension, it would act to control or slow down the extension of these fingers and the hand at the wrist joint, not flexion. This makes option A correct, as it describes the muscle's action in controlling the opposite movement (extension) to its primary function (flexion).
