What is the specific name for the plane that divides the body into left and right halves when halves are equal?

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

Answer: (D)

The midline-specific plane that divides the body into equal left and right halves is the midsagittal plane, also called the median plane. In anatomy, sagittal planes run vertically from front to back and are parallel to the body’s midline. When a sagittal plane passes exactly through the midline, it creates two equal halves, which is what defines the midsagittal plane. If a sagittal plane is offset from the midline, the left and right portions aren’t equal. The frontal plane, by contrast, splits the body into front and back portions, and the transverse plane divides it into upper and lower portions.
