As we learned in the rat dissection lab one of the main differences between rats and humans is orientation and direction. the dorsal side of a rat points in the upwards direction though in humans the dorsal side is the same as the direction.

The correct answer is: Posterior

Explanation:

In the anatomy of humans, the standardized anatomical terms of location are used to precisely describe and transfer the information of the animal bodies and their organs.

The term posterior refers to the back or located towards the back of body of the organism.  

The term dorsal surface refers to the upper side or back of the organism.

Therefore, in humans the dorsal side is the same as the posterior direction.

emerging idea only occurs as a raw idea that could appear out of nowhere. meanwhile, to reach scientific consensus , that idea must be structured and tested over and over again through various experiments. the scientific consensus transforms the raw idea into idea that is more reliable through the process of scientific elimination.
