What does abduction refer to in terms of body movement?

Abduction refers to the movement of a limb or body part away from the midline of the body. This action is important in various physical activities and body mechanics. For instance, when you raise your arms laterally to the sides, you are performing abduction of the arms. Understanding this term is crucial for healthcare professionals, including CNAs, as it aids in assessing a patient's mobility and developing appropriate care plans.

The other choices describe different types of movement. Movement toward the midline corresponds to adduction, which is the opposite of abduction. Circular motion could refer to actions like rotation, while movement backward would typically be referred to as retraction or extension, depending on the context. Hence, recognizing abduction as movement away from the midline helps differentiate it from these other related terms.
