The anatomical term "external" refers to something

• A. Outward from the center of the body
• B. Toward the outside of the body
• C. Toward the back of the body
• D. Inside the body

Answer: (B)

External describes location on or toward the outside surface of the body, i.e., toward the exterior rather than the interior. This makes it the best fit for “toward the outside of the body.” It’s not about the back (posterior) or being inside; those would describe different directions.
