Which plane divides the body into left and right halves?

• A. Frontal plane
• B. Sagittal plane
• C. Coronal plane
• D. Transverse plane

Answer: (B)

Planes of the body describe how sections are oriented. The one that splits the body into left and right sides is the sagittal plane. It runs vertically from front to back, and when it passes exactly through the midline, it’s the midsagittal (or median) plane that creates equal left and right halves. In contrast, the frontal (coronal) plane divides the body into front and back parts, and the transverse (horizontal) plane divides it into top and bottom parts.
