What term indicates a patient is lying horizontally with the face and trunk upward?

The term that indicates a patient is lying horizontally with the face and trunk upward is "supine." In this position, the individual’s back is on the ground or surface they are lying on, with their face directed towards the sky or ceiling. This position is commonly used in medical settings for various examinations and treatments because it provides access to the front of the body and is comfortable for patients during certain procedures.

In contrast, the term “prone” refers to lying face down, while “standing” describes an upright position and “sitting” indicates a position where the person is on their buttocks with their back straight and knees bent. Understanding these terms is essential for effective communication in physical therapy and patient care.
