Adduction

Adductio

Definition

Adduction is defined as the movement of a limb or appendage, towards the midline.

For instance, when the hand is placed in a normal anatomical position, the inward movement of the index finger towards the midline (i.e. middle finger) and the movement of ring and little fingers towards the midline (or middle finger), are both examples of adduction movements of the fingers. Similarly, bringing the arms downwards and inwards towards the sides of the body is also an example of adduction.

The opposite of adduction is abduction, where the limb or the appendage moves away from the midline.
