The vagus is the longest nerve of the autonomic nervous system in the human body and comprises both sensory and motor fibers. The sensory fibers have their nuclei either in the jugular or the nodose ganglion , whereas the motor fibers come from neurons of the dorsal motor nucleus of the vagus and the nucleus ambiguus .

The two branches of the autonomic nervous system work together to increase or slow the heart rate. The vagus nerve acts on the sinoatrial node, slowing its conduction and modulating vagal tone, via the neurotransmitter acetylcholine and downstream changes to ionic currents and calcium of heart cells.

The Power of the Vagus Nerve. The vagus nerve is part of the parasympathetic nervous system, often called the “rest and digest” system because it helps the body relax after periods of stress ...
The vagus, or tenth cranial nerve, is a primary component of the autonomic nervous system, which operates the internal organs.It transmits parasympathetic signals to and from the heart, lungs, and digestive tract. [15]
"Calming the vagus nerve with deep breathing and taking time for meals regulates this pathway," Moore says. "Identifying triggers, taking a break, identifying and communicating needs, finding joy ...
The vagus nerve is the longest nerve of the autonomic nervous system and helps regulate many critical aspects of human physiology, including heart rate, blood pressure, sweating, and digestion through the release of acetylcholine. Common maneuvers that activate the vagus nerve include the Valsalva maneuver and carotid sinus massage, which can ...
“But your gut is connected to the central nervous system, largely via the vagus nerve. With that vagus nerve integration, it speeds up your bowel or slows it down and kind of sends extra signals ...
Vagus nerve stimulation (VNS) is a medical treatment that involves delivering electrical impulses to the vagus nerve. It is used as an add-on treatment for certain types of intractable epilepsy , cluster headaches, treatment-resistant depression and stroke rehabilitation.
