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]
Lateral medullary syndrome is a neurological disorder causing a range of symptoms due to ischemia in the lateral part of the medulla oblongata in the brainstem. The ischemia is a result of a blockage most commonly in the vertebral artery or the posterior inferior cerebellar artery. [1] Lateral medullary syndrome is also called Wallenberg's ...
Laryngeal cancer can present with pain behind the ear and in the ear - this is a referred pain through the vagus nerve to the nerve of Arnold. In a small portion of individuals, the auricular nerve is the afferent limb of the Ear-Cough or Arnold Reflex. [ 3 ] Physical stimulation of the external acoustic meatus innervated by the auricular nerve ...
Referred pain, also called reflective pain, [1] is pain perceived at a location other than the site of the painful stimulus.An example is the case of angina pectoris brought on by a myocardial infarction (heart attack), where pain is often felt in the left side of neck, left shoulder, and back rather than in the thorax (chest), the site of the injury.
The recurrent laryngeal nerve (RLN) is a branch of the vagus nerve (cranial nerve X) that supplies all the intrinsic muscles of the larynx, with the exception of the cricothyroid muscles. There are two recurrent laryngeal nerves, right and left. The right and left nerves are not symmetrical, with the left nerve looping under the aortic arch ...
Symptoms that affect the sensory and motor systems seem to develop symmetrically. For example, if the right foot is affected, the left foot is affected simultaneously or soon becomes affected. [1] In most cases, the legs are affected first, followed by the arms. The hands usually become involved when the symptoms reach above the ankle. [3]
Anatomical terms of neuroanatomy. [edit on Wikidata] The anterior vagal trunk is one of the two divisions (the other being the posterior vagal trunk) into which the vagus nerve splits as it passes through the esophageal hiatus to enter the abdominal cavity. [1] The anterior and posterior vagal trunks represent the inferior continuation of the ...
Neurology. Morton's neuroma is a benign neuroma of an intermetatarsal plantar nerve, most commonly of the second and third intermetatarsal spaces (between the second/third and third/fourth metatarsal heads; the first is of the big toe), which results in the entrapment of the affected nerve. The main symptoms are pain and/or numbness, sometimes ...
