Which of the following describes "retraction" in terms of body movement?

Retraction is defined as the backward movement of a body part, particularly in the context of the shoulder girdle or the jaw. This action contrasts with protraction, which involves moving a body part forward. For example, when you pull your shoulders back or move your jaw back towards your throat, you are performing retraction. This movement is essential in various physical activities and contributes to proper posture and alignment of the body. Understanding retraction is important in fields such as anatomy, kinesiology, and physical therapy as it relates to functional movement patterns and the mechanics of the body.
