The difference between being prone and being supine?
These guys are right, but also keep in mind that the palms need to be facing the same direction as the face if youre considering those terms for anatomical work
Prone is lying on your stomach, facing down. Supine is laying on your back facing up. I remember that SUPINE-U=SPINE as in you are lying on your spine.
A prone position is when someone lays on their belly. a supine position is when they lay on their back.
