Vagus Nerve

The vagus nerve is a long, complex nerve that runs from the brainstem down to the abdomen, passing through various organs. It is a key part of the parasympathetic nervous system, helping regulate essential functions such as heart rate, digestion, and respiratory rate. The vagus nerve also conveys sensory information from internal organs back to the brain. Because of its extensive reach, it plays a vital role in maintaining the body's internal balance and responds to changes in the environment, influencing processes like relaxation, inflammation, and immune response.
