Which plane divides the body into left and right parts?

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

Answer: (C)

Anatomical planes describe how the body can be divided in space. The plane that runs vertically from front to back and is parallel to the body's midline divides the body into left and right portions. This is the sagittal plane. If it passes exactly along the midline, it creates equal left and right halves (midsagittal or medial plane); if it’s offset from the midline, it’s a parasagittal plane. The transverse plane cuts across to separate top from bottom, while the frontal (coronal) plane divides front from back. So the left-right division is characteristic of the sagittal plane.
