The Vagus Nerve

The vagus nerve is a key part of the body's nervous system, acting as a communication highway between your brain and many vital organs in the chest and abdomen, including the heart, lungs, stomach, and intestines. It helps regulate essential functions such as heart rate, breathing, digestion, and mood. As the longest cranial nerve, it extends from the brainstem down to the abdomen, influencing both unconscious processes and some voluntary actions like swallowing. Its proper functioning is crucial for maintaining overall health and balance within the body's autonomic nervous system.
