What term is used to describe the position of lying face down?

The term used to describe the position of lying face down is "prone." In the prone position, the body is horizontal and facing downward, which is commonly utilized in various medical examinations and procedures. This position can facilitate access to certain areas of the body and is also significant in physical therapy and exercise contexts for targeting specific muscle groups.

In contrast, the supine position refers to lying on the back, which is the opposite of prone. The lateral position involves lying on the side, while recumbent generally means lying down in any position but is often interpreted as lying back. Therefore, "prone" accurately identifies the specific orientation of the body as face down.
