What is the definition of adduction in terms of body movement?

Adduction refers specifically to the movement of a body part toward the midline of the body. This term is often used in anatomical contexts to describe actions involving limbs or other parts. For instance, when you bring your arms down to your sides after raising them, or when you pull your legs together, you are performing adduction. This action contrasts with abduction, which is the movement of a body part away from the midline. Understanding this concept is essential in fields such as anatomy, physiology, and kinesiology, as it helps in describing movements accurately during both assessment and treatment roles in healthcare and fitness contexts.
