Which plane divides the body into unequal halves?

• A. Coronal plane
• B. Sagittal plane
• C. Parasagittal plane
• D. Axial plane

Answer: (C)

Parasagittal plane divides the body into unequal halves because it is a sagittal plane that runs parallel to the midline but is offset from it. Any sagittal plane splits the body into left and right portions; when it passes through the midline, those portions are equal (midsagittal/median plane). When the plane is offset from the midline, the left and right parts are different sizes, producing unequal halves. The coronal plane cuts front from back, and the axial plane cuts top from bottom, so they don’t describe left-right equality.
