Which anatomical plane divides the body into anterior and posterior sections?

The anatomical 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 and allows for the division of the body into these two distinct sections. It is crucial in anatomy as it helps in understanding the orientation and various body positions relating to medical imaging and surgical procedures.

The other options refer to different types of anatomical planes: the sagittal plane divides the body into left and right sections, the transverse plane separates the body into upper (superior) and lower (inferior) parts, and the horizontal plane is synonymous with the transverse plane but does not specifically describe the anterior and posterior division. Therefore, the coronal plane is the correct designation for the division of the body into anterior and posterior sections.
