Which term describes the plane that divides the body into anterior and posterior sections?

The term that describes the plane that divides the body into anterior (front) and posterior (back) sections is "coronal." This plane runs vertically from side to side and is also referred to as the frontal plane. It is crucial in anatomy and biomechanics for understanding how various movements occur and how forces are distributed across the body.

In contrast, the other terms refer to different anatomical planes. The transverse plane divides the body into superior (upper) and inferior (lower) sections, while the sagittal plane splits the body into left and right sections. The term "horizontal" is often used to refer to planes that are parallel to the ground, which can sometimes overlap with the definition of the transverse plane but does not specifically define anterior and posterior divisions. Understanding these distinctions is fundamental in the field of clinical biomechanics, particularly in analyzing movement and posture.
