This tag is used primarly for two things:

* For the neutral/common meaning of cross-section, such as post #462991;
* For when the act of [[sex]] is shown in a separate frame to show the internal anatomy of the participant(s). For example, a depiction of [[vaginal]] intercourse where the vagina, cervix, and uterus are visible.

Use [[x-ray]] instead of this tag for when the internal anatomy is visible through the body as if by x-ray vision, as opposed to being drawn in a separate frame.
