Which muscle draws the fingers together at their base?

The muscle that draws the fingers together at their base is known as the adductor. This type of muscle is specifically responsible for movements that bring parts of the body closer together, which in this case involves pulling the fingers inward towards the midline of the hand.

In contrast, the abductor muscle, as its name suggests, performs the opposite action by moving the fingers apart from each other. The extensor muscle is primarily involved in the extension of the fingers, allowing them to straighten out away from a flexed position. The flexor muscle, on the other hand, is responsible for bending the fingers. Understanding these distinctions is crucial in grasping the various functions of muscles in the hand, as they play a significant role in many tasks performed by nail technicians and others in the field of cosmetology.
