The vagus nerve is also responsible for regulating inflammation in the body, via the inflammatory reflex. [7] Efferent vagus nerve fibers innervating the pharynx and back of the throat are responsible for the gag reflex. In addition, 5-HT 3 receptor-mediated afferent vagus stimulation in the gut due to gastroenteritis is a cause of vomiting. [8]
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 inflammatory reflex is a neural circuit that regulates the immune response to injury and invasion. All reflexes have an afferent and efferent arc. The Inflammatory reflex has a sensory afferent arc, which is activated by cytokines and a motor or efferent arc, which transmits action potentials in the vagus nerve to suppress cytokine production.
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 ...
Vagal tone is activity of the vagus nerve (the 10th cranial nerve) and a fundamental component of the parasympathetic branch of the autonomic nervous system. This branch of the nervous system is not under conscious control and is largely responsible for the regulation of several body compartments at rest.
The findings align with prior research suggesting that misfolded alpha-synuclein proteins may spread from the gut to the brain via the vagus nerve, offering further support for the hypothesis that ...
"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, named after the Latin word vagus (because the nerve controls such a broad range of target tissues – vagus in Latin literally means "wandering"), contains parasympathetic fibers that originate in the dorsal nucleus of the vagus nerve and the nucleus ambiguus in the CNS. The vagus nerve can be readily identified in the neck ...
