How does the frontal plane divide the body?

• A. Anterior and posterior (front and back)
• B. Left and right halves
• C. Superior and inferior
• D. Proximal and distal

Answer: (A)

The frontal plane, also called the coronal plane, runs vertically and divides the body into front (anterior/ventral) and back (posterior/dorsal) parts. This orientation is perpendicular to the sagittal plane, which splits left from right, and to the transverse (horizontal) plane, which splits upper from lower. In practical terms, when you imagine a cut that separates the belly side from the back, you’re looking at the frontal plane. The other terms describe different ideas: left-right halves come from the sagittal division, upper-lower halves come from the transverse division, and proximal/distal relate to positions along limbs rather than a plane.
