Which plane divides the body into superior (upper) and inferior (lower) portions in the described material?

Which plane divides the body into superior (upper) and inferior (lower) portions in the described material?

• A. Horizontal Plane
• B. Frontal Plane
• C. Midsagittal Plane
• D. Dorsal Cavity

Answer: (A)

The plane that yields top and bottom portions is the horizontal plane, also called the transverse plane. It runs left to right across the body, slicing it perpendicular to the long axis so what’s above the plane is the superior portion and what’s below is the inferior portion. Think of a cross-section through the body at the waist or neck—the cut separates what’s on the top from what’s on the bottom. The frontal (coronal) plane, on the other hand, splits the body into front (anterior) and back (posterior) parts. The midsagittal plane divides the body into left and right halves. The dorsal cavity is a body cavity, not a plane.
