Which term describes the left-right midline plane of the body?

• A. Rostrum
• B. Transverse
• C. Median
• D. Dorsum

Answer: (C)

The left-right midline plane is the median plane. It runs vertically through the body's midline and divides it into equal left and right halves. This is the midsagittal plane—the specific sagittal plane that passes exactly along the midline. A transverse plane is horizontal and separates the body's cranial and caudal parts, not left and right. The dorsum refers to the back surface, and the rostrum is the snout.
