Which plane divides the body into right and left portions and may be equal or unequal?

• A. Sagittal Plane
• B. Midsagittal Plane
• C. Parasagittal Plane
• D. Frontal Plane

Answer: (A)

Think of how planes slice the body. The plane that divides the body into right and left portions runs vertically and is aligned with the body's midline. This is the sagittal plane. If that vertical cut goes exactly along the midline, it splits the body into two equal halves—the midsagittal plane. If the cut is parallel to the midline but offset to one side, the left and right sides are unequal—the parasagittal plane. The frontal (coronal) plane, in contrast, separates front (anterior) from back (posterior). So, for dividing into right and left parts, the sagittal plane is the general term, with the equal or unequal cases defined by midsagittal and parasagittal.
