What does the midsagittal plane do?

• A. Divides the body into equal left and right halves
• B. Divides the body into anterior and posterior sections
• C. Divides the body into upper and lower sections
• D. Divides the body into proximal and distal segments

Answer: (A)

Anatomical planes classify how a body can be sectioned to study or describe locations. The midsagittal plane is a specific sagittal plane that runs down the midline from head to toe, so it divides the body into equal left and right halves. That equal split is what makes it distinct from other planes. Dividing the body into front and back is the frontal (coronal) plane, which separates anterior from posterior. Dividing into upper and lower is the transverse (horizontal) plane. Proximal and distal describe positions along a limb rather than a plane of division.
