Which statement best describes an anterior structure relative to another structure?

• A. Lies in front of the other structure.
• B. Lies behind the other structure.
• C. Is closer to the body's centerline.
• D. Is higher than the other structure.

Answer: (A)

Anterior means toward the front of the body. So when one structure lies in front of another, it is anterior relative to that structure. The opposite would be behind (posterior). The idea of being closer to the body's centerline describes medial, not anterior, and being higher describes superior. Therefore, stating that the structure lies in front of the other best captures an anterior relationship.
