Which terms are synonyms in four-legged animals?

• A. Rostral and Anterior
• B. Caudal and Dorsal
• C. Ventral and Posterior
• D. Left and Right

Answer: (A)

In four-legged animals, directions along the length of the body are described with front-to-back terms. Rostral means toward the nose, and in quadrupeds that direction lines up with the front of the body, which is described as anterior. So rostral and anterior point to the same direction on a four-legged animal. The other pairs refer to different axes: caudal is toward the tail while dorsal is toward the back, so they’re not synonyms. Ventral is toward the belly and posterior toward the rear, so they describe different orientations. Left and right are opposite sides, not interchangeable.
