Which of the following body positions has the palms facing down?

The body position in which the palms are facing down is known as the prone position. In this orientation, a person lies flat on their stomach, which naturally places the palms down against the surface. This position is often used in medical assessments, treatments, or procedures where access to the back of the body is needed.

In contrast, the supine position involves lying on the back with the palms facing up, making it distinct from the prone position. The seated position typically allows for a neutral arm placement, meaning the palms can face forward or back depending on the person's posture, while standing also permits a variety of arm placements but does not inherently involve the palms facing down. Understanding these body positions is crucial for medical professionals, as they inform how to conduct examinations and treatments appropriately.
