What is the primary function of adductors in the hand?

1. To extend the fingers

2. To flex the wrist

3. To draw the fingers together

4. To rotate the thumb

The correct answer is: To draw the fingers together

The primary function of adductors in the hand is to draw the fingers together. The term "adductors" refers to muscles that facilitate the movement of body parts toward the midline of the body or closer to each other. In the context of the hand, the adductor muscles are specifically responsible for the adduction of the fingers, which means they bring the fingers closer together. This action is essential for grasping objects and performing detailed tasks that require finger coordination. In contrast, functions like extending the fingers or flexing the wrist involve different muscle groups, such as the extensor and flexor muscles. Additionally, the action of rotating the thumb is more closely associated with muscles responsible for opposition and rotation rather than adduction. Therefore, the role of adductors in the hand is crucial for maintaining proper hand function and dexterity through the movement of fingers towards one another.
