There could be many answers!
But I think you are referring to the DIAPHRAGM (the main muscle of breathing) which separates the THORAX (your 'chest') from your ABDOMEN (your 'stomach' area)
The plane that divides the body into the superior and inferior sections is called the transverse plane
Superior and inferior portions
inferior, middle, superior
The answer in the Transverse Plane.
Visualize: Body laying on the back with palms up...what you see is anterior, or the front. What is underneath is considered posterior, or the back.
The three sections of turbinates in the nasal cavity are the superior, middle, and inferior turbinates. They are responsible for filtering, humidifying, and warming air as it passes through the nasal passages.
well all the body planes separate the body into two planes. the frontal plane separates it into anterior(front) and posterior(back) sagital separates medial and lateral, transverse superior and inferior.
This would involve a transverse cut.
transverse plane
Axial plane (Transverse Plane) which is a horizontal plane that divides the body or any of its parts into upper and lower parts. If you mean the entire body, it runs horizontality through the umbilicus or navel.
The relative superior endpoint of the nasopharynx is the skull base, which separates it from the base of the skull. The relative inferior endpoint is the upper surface of the soft palate, which forms the boundary between the nasopharynx and the oropharynx.
Inferior. :) Inferior = below Superior = above
