Which plane divides the body into right and left halves?

• A. Frontal Plane
• B. Transverse Plane
• C. Diagonal Plane
• D. Sagittal Plane

Answer: (D)

The sagittal plane runs vertically from front to back and divides the body into left and right portions. When it passes through the body's midline, it creates equal left and right halves—the mid-sagittal or median plane. That’s why this plane is the one that best fits the idea of splitting the body into right and left halves. In contrast, the frontal (coronal) plane separates front from back, the transverse (horizontal) plane separates top from bottom, and the diagonal (oblique) plane cuts at an angle and doesn’t specifically define left-right halves.
