HUMAN NUTRITION

Detailed explanation-1: -Thus, anterior and posterior indicate front and back; rostral and caudal, toward the head and tail; dorsal and ventral, top and bottom; and medial and lateral, the midline or to the side. Nevertheless, the comparison between these coordinates in the body versus the brain can be confusing.

Detailed explanation-2: -Anatomically, there are four main positions: supine, prone, right lateral recumbent, and left lateral recumbent. It is important to note that each position has its medical implications. The supine position requires the face and upper body to be turned upwards in a horizontal position.

Detailed explanation-3: -Dorsal and ventral are sometimes used in place of anterior and posterior, respectively. Dorsal means the back side or upper side, while ventral means the frontal or lower side. These are mostly used with animal anatomy, but can be used in human anatomy as long as they are describing the side of an appendage.

Detailed explanation-4: -Anatomical Directional Terms: Medial, lateral, superior, inferior, anterior, posterior, proximal, distal, superficial, deep, unilateral, bilateral, ipsilateral, and contralateral.
