In four-legged animals, which term describes toward the head end?

• A. Rostral
• B. Anterior
• C. Dorsal
• D. Ventral

Answer: (A)

In four-legged animals, directions along the body are described with reference to the head-to-tail axis, and the term rostral specifies toward the nose end. Rostral comes from the idea of the rostrum or snout, so it directly marks the direction toward the head or snout along the body's long axis. The opposite direction is caudal. Dorsal and ventral describe top/bottom relative to the back and belly, not toward the head. Anterior can mean toward the head in humans, but for quadrupeds rostral is the standard way to denote headward direction and fits the animal’s outward orientation.
