Adduction is defined as:

Adduction is indeed defined as the movement toward the midline of the body. This term is often used in anatomy to describe how limbs or other body parts move inward towards the center of the body. For example, when a person raises their arms to the side and then brings them down to their sides, that action is an example of adduction.

Understanding this concept is crucial for those studying anatomy and physiology, as well as for healthcare professionals working with patients. It helps in assessing mobility, creating exercise plans, and rehabilitating injuries where movement patterns are involved. The other terms related to motion, like abduction (movement away from the body), extension (straightening), and circular movement, each describe different types of movements and are not synonymous with adduction.
