A postcard of a woman on a beach in prone position. In anatomy, the prone position is a position of the human body lying face down. It is opposed to the supine position which is face up. Using the terms defined in the anatomical position, the ventral side is down, and the dorsal side is up.
When in lying position, the body may assume a great variety of shapes and positions. The following are the basic recognized positions: Supine position: lying on the back with the face up; Prone position: lying on the chest with the face down ("lying down" or "going prone") Lying on either side, with the body straight or bent/curled forward or ...
Supine position and prone position. The supine position (/ ˈ s uː p aɪ n /) means lying horizontally with the face and torso facing up, as opposed to the prone position, which is face down. When used in surgical procedures, it grants access to the peritoneal, thoracic and pericardial regions; as well as the head, neck and extremities.
Supine: lying on the back on the ground with the face up. Prone: lying on the chest with the face down ("lying down" or "going prone"). See also "Prostration". Lying on either side, with the body straight or bent/curled forward or backward. The fetal position is lying or sitting curled, with limbs close to the torso and the head close to the knees.
Unlike the situation in other vertebrates, the limbs are placed in positions reminiscent of the supine position imposed on cadavers during autopsy. Therefore, the body has its feet together (or slightly separated), and its arms are rotated outward so that the palms are forward, and the thumbs are pointed away from the body (forearms supine). As ...

Pronation and supination refer generally to the prone (facing down) or supine (facing up) positions. In the extremities, they are the rotation of the forearm or foot so that in the standard anatomical position the palm or sole is facing anteriorly when in supination and posteriorly when in pronation.

It is increased in supine position and decreased in prone position, and is on average higher and more pronounced during the day as compared to the night. [22] RSA has also been extensively used to quantify vagal tone withdrawal in graded orthostatic tilt .
