When massaging the hands and arms, what muscles would you affect?

Massaging the hands and arms primarily influences the muscles involved in the movements of the forearm and hand. The correct answer highlights the pronators, supinators, flexors, and extensors, which are key muscle groups in these areas.

The pronators are responsible for turning the palm down, while the supinators perform the opposite action, rotating the palm up. The flexors are the muscles that facilitate bending at the wrist and fingers, enabling gripping and holding objects. Conversely, the extensors work to straighten the wrist and fingers. When massaging these areas, manipulation of these muscles can help alleviate tension, improve circulation, and enhance overall function.

The other options refer to muscle groups that are not primarily engaged in the movement of the hands and arms. The deltoids, triceps, and biceps involve the shoulder and upper arm rather than specifically focusing on the hand and arm. The quadriceps, hamstrings, and calves pertain to the lower body, and the abdominals, obliques, and latissimus dorsi are centered around the torso and back. Therefore, the selection that encompasses the pronators, supinators, flexors, and extensors is the most relevant in the context of hand and
