What does protraction mean in the context of movement?

In the context of movement, protraction refers to the movement of a body part forward, typically in the horizontal plane. This term is often used to describe actions involving the scapulae (shoulder blades) and the mandible (jaw). When the scapula is protracted, it moves away from the midline of the body, as seen in actions like reaching forward or pushing something away.

This movement is significant in various physical activities and rehabilitation settings because it helps to understand how different body parts interact and function together. For instance, protraction of the shoulders can be important during specific exercises or while maintaining proper posture. Recognizing protraction is essential for evaluating movement patterns and ensuring safety during physical activity.
