Which plane is parallel to the ground and divides the brain into superior and inferior parts?

• A. Axial (Horizontal) Plane
• B. Sagittal Plane
• C. Coronal Plane
• D. Transverse Plane

Answer: (A)

Think about how slices are oriented in the brain relative to gravity. A plane that runs parallel to the ground will separate top from bottom, giving us superior and inferior parts. In brain anatomy, that plane is the axial plane, also called horizontal, and it’s the standard way to divide the brain into upper and lower portions. Some texts also use the term transverse for the same orientation, but the axial description is the one used here. The other planes slice in different directions: the sagittal plane splits left from right, and the coronal plane splits front from back. Thus, the plane parallel to the ground that yields a top-versus-bottom division is the axial plane.
