What term means closest to the point of origin?

What term means closest to the point of origin?

• A. Distal
• B. Frontal plane
• C. Lateral
• D. Proximal

Answer: (D)

When describing where something is in relation to where a limb attaches to the body, the word used for the part closest to that attachment is proximal. Proximal means nearest to the point of origin, such as where the limb attaches to the trunk. The opposite, distal, means farther away from that origin. For example, the elbow is proximal to the wrist, while the wrist is distal to the elbow. The other options don’t describe proximity to the origin: the frontal plane is a reference plane dividing front and back, and lateral means away from the midline. Therefore, the term closest to the point of origin is proximal.
