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 frontal plane, also referred to as the coronal plane. This plane runs vertically from side to side, creating a division that allows for the examination or analysis of body structures either toward the front or toward the back.

In anatomical terms, the frontal plane is essential for understanding body movement and orientation, particularly in activities such as lateral raises or side lunges, where the movements occur within this plane.

In contrast, the sagittal plane divides the body into left and right sections, while the transverse plane separates the body into upper and lower portions. The diagonal plane does not represent a standard anatomical classification and is generally used to describe various angles of movement rather than a specific separation of body sections.
