In humans and in animals, the correct position of tissues, organs and appendages is essential. Two body axes (the head-tail and the back-belly axes) usually define this position by generating a coordinate system, which supplies each cell in the body with its precise address. Thus, for example, the vertebrate central nervous system is always located on the back, and the intestinal tract on the belly of the animal.
