Quizplus · Accepted Answer

The term "dorsal interossei manus" refers to the muscles located between the bones of the hand (metacarpals) on the backside (dorsal) of the hand. The dorsal interossei manus are responsible for abduction (spreading apart) of the fingers. There are four dorsal interossei manus, and each one is associated with a specific set of fingers. The dorsal interossei manus associated with fingers two, three, and four (index, middle, and ring) are grouped together, while the dorsal interossei manus associated with the little finger are separate. Therefore, the dorsal interossei manus can move fingers two, three, and four (option B).
