For the thumb, abduction is the anterior movement that brings the thumb to a 90° perpendicular position, pointing straight out from the palm. Adduction moves the thumb back to the anatomical position, next to the index finger. Abduction and adduction movements are seen at condyloid, saddle, and ball-and-socket joints (see Figure 9.12e).
Abduction of the wrist has it moving away from the body’s midline, in the same direction as arm abduction. Adduction of the wrist has it going in the opposite direction, toward the body’s midline.

Abduction is defined as the movement of a limb or appendage, away from midline.For instance, when the hand is placed in the normal anatomical position, the outward movement of the index finger away from the midline (i.e. middle finger) and the movement of ring and little fingers away from the midline (or middle finger), are both examples of abduction movements of the fingers. Similarly ...
