Where Is The Vagus Nerve And What Does It Do

And it oversees a vast range of crucial functions communicating motor and.

The vagus nerve the longest of the cranial nerves controls your inner nerve center the parasympathetic nervous system. It is the longest nerve of the autonomic nervous system in the human body and comprises sensory and motor fibers. Vagus nerve relays motor nerve impulses to different muscles such as those of the tongue and voice box. It sends sensory information to the brain and controls certain motor functions throughout the body.

The vagus nerve historically cited as the pneumogastric nerve is the tenth cranial nerve or cn x and interfaces with the parasympathetic control of the heart lungs and digestive tract. When the brain triggers parasympathetic activation the vagus nerve carries the messages to the heart decreasing the heart rate and blood pressure to the lungs to constrict the respiratory passageways to every organ in the digestive system to increase motility and blood flow to the digestive tract to promote defecation to the kidneys and bladder to promote urination and to reproductive organs to aid in sexual arousal. When the brain triggers parasympathetic activation the vagus nerve carries the messages to the heart decreasing the heart rate and blood pressure to the lungs to constrict the respiratory passageways to every organ in the digestive system to increase motility and blood flow to the digestive tract to promote defecation to the kidneys and bladder to promote urination and to reproductive organs to aid in sexual arousal. The sensory fibers originate from neurons of the nodose ganglion whereas the motor fibers come from neurons of the dorsal.

The vagus nerve is one of the cranial nerves that connect the brain to the body. It is among the longest of cranial nerves. It carries both motor and sensory information and it supplies innervation to the heart major blood vessels airways lungs esophagus stomach and intestines. Moreover these pairs of nerves all arise directly from the brain including the brainstem it contains both sensory and motor fibers.

The vagus nerves are normally referred to in the singular. It also receives sensory impulses from throat organs of abdomen and chest as well as ear. The vagus nerve also known as the 10th cranial nerve or cn x is a very long nerve that originates in the brain stem and extends down through the neck and into the chest and abdomen. It is also a part of the autonomic nervous system.

The vagus nerve has two bunches of sensory nerve cell bodies and it connects the brainstem to the body. The vagus nerve comes as the longest of 12 cranial nerves. The vagus nerve also supplies visceral nerve impulses to abdomen organs chest organs and glands of throat. When it overreacts it can cause a sudden drop in heart rate and blood pressure resulting in.
