Abduction refers to a motion that pulls a structure or part away from the midline of the body (the center of the body is defined as the midsagittal plane). For example, raising the arms up, such as when walking on a tightrope, is an example of abduction at the shoulder. In the case of fingers and toes, it refers to spreading the digits apart, away from the centerline of the hand or foot. Abduction of the wrist is also called radial deviation.
HINT: It can help to pronounce abduction as “AB-duction” since abduction and adduction sound similar. A way to remember this is that the bump of the “b” in abduction faces away from the “A” just like the movement in abduction is away from the body.
