Quizplus · Accepted Answer

The dorsal interossei pedis are muscles located on the top of the foot between the toes. Their primary action is to extend the toes at the interphalangeal joints, which is option A. They do not have any involvement in plantarflexion of the foot or extension of the fingers. Option C is incorrect because the dorsal interossei pedis only extend toes two through four, not all five toes.
