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. [4]
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 and regulates bodily functions ...
Stimulation of the efferent vagus nerve slows heart rate, induces gastrointestinal motility, and inhibits TNF production in spleen. [1] Stimulation of the efferent pathway of the vagus nerve releases acetylcholine, the neurotransmitter which interacts with the α7 subunit of the nicotinic AChR (α7 nAChR). nAChR is expressed on the cell ...
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 .

A vagal maneuver is an action used to stimulate the parasympathetic nervous system by activating the vagus nerve.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.
Oprah Winfrey confessed she was very "nervous" about her recent interview with Elliot Page and shared the important research she did ahead of their chat. Why Oprah Winfrey Was "More Nervous Than ...
So it’s only fitting that Gorman wrote a poem in recognition of Oprah’s 70th birthday, January 29, 2024. Watch Gorman read her moving words here, and read the full piece below.
This discovery that the vagus nerve controls the immune system led him to study the effects of stimulating the vagus nerve with electrodes to alleviate inflammation, called "the inflammatory reflex". [10] [11] [12] In 2007 he co-founded a company called SetPoint Medical which aimed to develop vagus nerve stimulation devices to treat autoimmune ...
