Which plane divides the body into anterior and posterior sections?

The plane that divides the body into anterior (front) and posterior (back) sections is known as the coronal plane. This plane runs vertically from side to side, separating the body into a front part and a back part. This differentiation is crucial in medical and anatomical contexts, as it helps in understanding the location of organs and structures in relation to each other.

The transverse plane, on the other hand, divides the body into superior (upper) and inferior (lower) portions, which is distinctly different from the anterior and posterior separation. The sagittal plane divides the body into left and right sections, again focusing on a different spatial orientation. Lastly, the term "horizontal plane" is often synonymous with the transverse plane in certain contexts but does not define the anterior-posterior division. Thus, the coronal plane is the correct answer as it directly addresses the question about separating the body into front and back sections.
