Adduction is the movement of a bone toward the midline of the body. Movement of the limbs inward after abduction is an example of adduction. Circumduction is the movement of a limb in a circular motion, as in swinging an arm around. Figure \(\PageIndex{1}\): Angular and rotational movements: Synovial joints give the body many ways in which to move.
Spreading the fingers or toes apart is also abduction, while bringing the fingers or toes together is adduction. 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.
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 11.10.1e).
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 ...

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 Figure9.5.1.e).
Abduction and adduction are usually side-to-side movements, such as moving the arm laterally when doing jumping jacks. Abduction: moving away from the body’s midline. Adduction: moving toward the body’s midline. The gluteus medius, gluteus minimus, tensor fasciae latae, and sartorius are muscles that abduct the hip.
