Final answer:
The term that describes motion at the joint surface is Arthrokinematics, which refers to movements like gliding that occur between joint surfaces.
Step-by-step explanation:
The correct term that best describes motion at the joint surface is Arthrokinematics (Option B). This term specifically pertains to the movement that occurs between joint surfaces, such as the sliding and gliding motions that cannot be observed directly but are critical for joint function. Osteokinematics, in contrast, describes the movement of bones around a joint axis, which is visible and measurable as the movement of body segments, such as the bending of the elbow. Kinetic motion is a more general term that refers to any movement due to forces, while range of motion refers to the full movement potential of a joint, usually measured in degrees.
