Dorsal

Real World Example

Imagine trying to pick up your backpack without knowing which side is the front or the back. Just like how it's crucial to identify the correct side of your backpack to properly carry it, organisms have a "dorsal" side, which is essentially their equivalent of a "back." In both cases, understanding which side is the "back" helps us handle and interact with them correctly; for a backpack, it's about comfort and functionality, while for an organism, it's about identifying anatomical orientation.
