Which plane is described as a vertical plane dividing the body into superior (upper) and inferior (lower) portions?

Which plane is described as a vertical plane dividing the body into superior (upper) and inferior (lower) portions?

• A. Frontal Plane
• B. Horizontal Plane
• C. Medial
• D. NIDCR

Answer: (A)

Planes describe how we slice the body to view different parts. The horizontal plane runs parallel to the ground and divides the body into upper (superior) and lower (inferior) portions. So when a description mentions dividing into top and bottom, it points to the horizontal plane. The frontal (coronal) plane, by contrast, is vertical and splits the body into anterior (in front) and posterior (behind) parts. Medial means toward the midline of the body, not about top and bottom, and NIDCR is just an acronym for a dental research institute, not a plane. In this case, the top-and-bottom division corresponds to the horizontal plane.
