Which term describes the movement of a limb away from the midline of the body?

The term that describes the movement of a limb away from the midline of the body is abduction. In human anatomy, abduction refers specifically to the action of moving a body part, typically an arm or a leg, outward away from the central axis of the body.

This movement is commonly observed when raising your arms sideways or moving your legs away from the body's center, which helps in performing various physical activities. In contrast, adduction describes the opposite movement, which is bringing a limb back toward the midline. Understanding these terms is fundamental in fields related to fitness and anatomy, as they help clarify the directions of movements during exercises or rehabilitation.

The other terms listed describe different movements. Elevation refers to raising a body part, while supination involves turning the palm forward or upward. None of these effectively describe the action of moving away from the midline, making abduction the correct term for this particular movement.
