Which term describes anterior displacement of a portion of the body without angular movement?

Explanation:
Protraction is anterior displacement of a body part without changing its angle, meaning the part slides forward in a straight path rather than bending. This translation occurs in movements like jutting the lower jaw forward or moving the shoulder blades forward along the thorax. Inversion and eversion refer to tilting the foot’s sole inward or outward, which involve different joints and rotations. Retraction is the opposite of protraction, pulling a part backward toward the midline. So the forward, non-rotational move described here is protraction.
