Final answer:
The horizontal plane dividing the body into superior and inferior parts is known as the transverse or horizontal plane.The horizontal plane that divides the body into superior and inferior portions is called the transverse plane. The transverse plane is perpendicular to the sagittal planes and the long axis of the body, and it produces cross-sectional images. It separates the body or an organ horizontally into upper and lower portions.
Step-by-step explanation:
The horizontal plane that divides the body into superior and inferior portions is called the transverse plane. The transverse plane can also be referred to as a horizontal plane, which is perpendicular to both the sagittal planes and the long axis of the body. This plane produces views known as cross sections.
In addition to the transverse plane, other important anatomical planes include the midsagittal plane, which divides the body into equal right and left halves, and the frontal plane (also known as a coronal plane), which separates the body into anterior and posterior portions.
