The body stands erect with the feet together and parallel; the arms are by the side, and the palms of the hands, the head, and the eyes all face directly forwards.
Relationships described in this position retain their validity no matter what position the body subsequently takes up.
For example, structures further away from the ground in the anatomical position are said to be superior to structures which are closer to the ground; the converse of superior is inferior. Thus the head is superior to the heart, and the heart is inferior to the head.
In descriptive embryology the word cranial is often used instead of superior, and the word caudal they be substituted for inferior.
Bodily planes transect the body, each perpendicular to the others.
