What is the median (midsagittal) plane?

• A. Divides the body into equal halves
• B. Divides the left and right halves
• C. Divides the body into unequal halves
• D. Divides front and back

Answer: (A)

The median (midsagittal) plane is the vertical plane that runs exactly along the body’s midline, dividing it into two equal left and right halves. That precise split into mirror-image halves is what defines it. It’s a specific sagittal plane; other sagittal planes may separate left and right parts but not into equal halves. A plane that divides front and back is the frontal (coronal) plane, not the midsagittal plane.
