Movement of a part backward is known as?

Movement of a part backward is referred to as retraction. This term is commonly used to describe the movement of body parts toward the center of the body or posteriorly. In the context of the shoulder blades, for example, retraction occurs when the shoulder blades move closer together, as can happen when pulling the shoulders back.

Understanding this concept is essential in fields such as physical therapy, sports medicine, and anatomy, where precise terms are used to describe movements of body parts. Protraction, on the other hand, involves moving a part forward, often used for movements of the shoulder or jaw. Extension refers to increasing the angle between parts, commonly associated with straightening limbs, while elevation involves lifting a body part superiorly, such as raising the shoulders. Each of these terms describes specific actions important for understanding human movement and function.
