In anatomical terms, what does abduction specifically refer to?

Abduction refers specifically to the movement of a body part away from the midline of the body. This term is commonly used in various contexts, including describing the movements of limbs. For instance, when the arms are lifted to the side, away from the torso, this movement is classified as abduction. Similarly, when the legs are moved apart, this is also considered abduction.

The definition clearly emphasizes the direction of movement relative to the midline, distinguishing it from related terms such as adduction, which describes the movement of a body part toward the midline. Understanding these terms is crucial in fields like anatomy and physical therapy, as they provide clarity in describing movements and can influence treatment plans and exercise prescriptions.
