The term "anterior" refers to a position located toward the front of the body or an object. In anatomy, it is often used to describe the location of structures in relation to one another. For example, the sternum is anterior to the heart, meaning the sternum is situated in front of the heart. In contrast to "anterior," the term "posterior" describes a position toward the back. Understanding these terms is essential in fields like medicine and biology, as they help professionals accurately describe the locations of organs and other body parts in relation to each other.
