Which position describes a person lying face down?

When a person is described as lying face down, the term used is "prone." This position is commonly utilized in various medical examinations and procedures, particularly when access to the back or posterior region of the body is required. Being in a prone position can also be beneficial for certain therapeutic treatments or exercise regimens that target specific muscle groups.

The other terms refer to different positions: "supine" describes someone lying on their back, which is the opposite of prone. "Lateral" indicates a side-lying position, while "sitting" refers to an upright position. Understanding these terms is essential for effective communication and accurate documentation in a medical setting.
