Which term is synonymous with transverse?

The term synonymous with "transverse" is "horizontal." This relationship stems from the orientation of both terms. Transverse describes something that runs across or is positioned horizontally in relation to the body or a given structure.

In medical and anatomical contexts, a transverse plane divides the body into upper (superior) and lower (inferior) sections, and this is a horizontal orientation. On the other hand, options like vertical and lateral describe orientations that are different from horizontal, with vertical referring to an up-and-down position and lateral indicating a sideward position. The median term pertains to a division along the midline, which is also distinct from horizontal or transverse orientations. Therefore, "horizontal" is the most accurate synonym for "transverse."
