Moving a body part forward and parallel to the ground.

Explanation:
Protraction is moving a body part forward along the horizontal plane. This is exactly what happens when you push your jaw or your shoulders forward, causing the scapula to glide anteriorly and stay parallel to the ground. It’s the forward counterpart to retraction, which pulls a part backward toward the midline, while elevation and depression are vertical movements—lifting up and lowering down, respectively. So the action described—moving forward and parallel to the ground—fits protraction most directly.
