The vagus nerve (located just behind the body, where we feel the pulse) is the longest nerve in the body. It is one of the 12 cranial nerves, extending from the brainstem to the abdominal cavity, and also passing through several organs, including the heart, esophagus, and lungs.

It is sometimes called “cranial nerve X” because it is part of the involuntary system that triggers unknown bodily functions, such as stabilizing heart rate and ensuring the functioning of actions.
