What section divides the body into anterior and posterior portions?

The section that divides the body into anterior (front) and posterior (back) portions is appropriately referred to as the frontal plane, which is also commonly known as the coronal plane. This anatomical plane runs vertically from side to side and separates the body into these two sections. The frontal plane is significant in various medical and anatomical contexts, as it helps in understanding the orientation of different body structures and organs when viewed from the front or back.

The other listed planes serve different functions: the transverse plane divides the body into superior (upper) and inferior (lower) parts, while the sagittal plane divides it into left and right portions. Understanding these different planes is crucial for accurate anatomical reference in both clinical and educational settings.
