Quizplus · Accepted Answer

The palmar interossei are responsible for adduction of fingers two, four, and five at the metacarpophalangeal joint. Therefore, an eccentric function of the palmar interossei would be to restrain or slow down abduction of these fingers at the same joint. Option B is the only choice that fits this description. The other options describe different movements that are not associated with the palmar interossei.
