What is the sagittal plane?

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

Answer: (A)

The sagittal plane is a vertical slice that runs from front to back and divides the body into left and right parts. If this slice goes exactly down the middle, it’s the midsagittal (median) plane, which creates equal left and right halves. Other planes are the frontal (coronal) plane, which splits front from back, and the transverse (horizontal) plane, which splits upper from lower. So this plane’s defining idea is left-right division, with equal halves only when it passes through the midline.
