What plane divides the body into upper and lower sections?

The sagittal plane divides the body into left and right sections, not upper and lower.

The frontal (coronal) plane divides the body into anterior and posterior (front and back) sections, not upper and lower.

The transverse plane cuts the body horizontally, separating it into a top and bottom half. It is also called the horizontal plane and is the only major anatomical plane oriented in this direction. Rotational movements occur in this plane.

The median plane is a specific mid-sagittal variant that divides the body into equal left and right halves, not upper and lower sections.
