Which plane divides the body into left and right halves?

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

Answer: (A)

Planes of the body are imaginary flat surfaces used to describe sections. The one that divides the body into left and right halves runs vertically from front to back. This is the sagittal plane. When it passes exactly along the midline, it creates equal left and right halves and is called the midsagittal or median plane. The coronal (frontal) plane splits the body into front and back portions, and the transverse plane splits it into upper and lower portions. Since the question focuses on left and right halves, the sagittal plane is the correct one.
