Which plane divides the body into a front half and a back half?

• A. Frontal Plane
• B. Sagittal Plane
• C. Transverse Plane
• D. Coronal Plane

Answer: (A)

The frontal plane, also called the coronal plane, divides the body into front (anterior) and back (posterior) parts. It runs vertically from head to toe and is perpendicular to the sagittal and transverse planes. This is how you separate what’s in the front of the body from what’s in the back. The sagittal plane splits left and right, and the transverse plane splits upper and lower, so they don’t produce a front/back division. The terms frontal and coronal are commonly used interchangeably to describe the same plane.
