What Is the Adductor Pollicis?
The adductor pollicis is a muscle in the hand that’s involved in movements of the thumb. Specifically, the muscle is used in thumb adduction, which is movement toward the plane of the palm .The adductor pollicis is made up of two separate heads which work together but have different origins. These are known as the oblique and transverse heads. Due to the two heads that make up the adductor pollicis, there are two different origins for the muscle. The transverse head has its origin on the third metacarpal bone, which is found in the hand. In contrast, the oblique head of the muscle originates via several different small bits of tissue, which attach to several metacarpals and the capitate bone. The capitate is a small bone found in the wrist.
