Role of the carotid body chemoreceptors in glucose

The carotid bodies CBs are multi-modal sensory organs located bilaterally at the bifurcation of the carotid artery and innervated by the carotid sinus nerve Hering’s nerve, a branch of the IX cranial nerve, While the CBs or embryologically analogous structures are well known as the dominant oxygen-sensing organ in vertebrates, in mammals there is evidence that the CBs may also …

Peripheral Chemoreceptors: Function and Plasticity of the

Introduction, The scientific history of peripheral chemoreceptors, especially that of the carotid body is often taken as beginning from the mid-18th century following the first recorded description, by Albrecht von Haller in 1762 of the “ganglion exiguum,” but could be argued to have begun earlier with the public defence of a dissertation describing the “ganglion minutuum” by his

Carotid body

Overview

CV Physiology

Aortic body chemoreceptors are found scattered along the aortic arch and innervated by the vagus nerve cranial nerve X, Because the carotid bodies have discrete locations on each external carotid, they have been studied the most, Each carotid body is a few millimeters in size and has the distinction of having the highest blood flow per tissue weight of any organ in the body; this high flow

Enhanced activity of carotid body chemoreceptors in

Discharge characteristics of the carotid body chemoreceptors in sham and CHF rabbits, The stimulus-response curves of single-unit activity of CB chemoreceptors to alterations in P O 2 were examined in eight sham and eight CHF rabbits, In the intact preparation, Pa O 2 was altered by ventilating the rabbits with 20% O 2-80% N 2, 15% O 2-85% N 2, 10% O 2-90% N 2, and 100% O 2 …

Chemoreceptors

Peripheral Chemoreceptors, Peripheral chemoreceptors are located in both the carotid body and the aortic body, They detect large changes in the partial pressure of oxygen pO 2 as the arterial blood supply leaves the heart, When low levels of oxygen are detected, afferent impulses travel via the glossopharyngeal and vagus nerves to the medulla oblongata and the pons in the brainstem,

Chemoreceptor – an overview

Carotid body chemoreceptors relay signals concerning arterial O 2 via the carotid sinus nerve to the nucleus of the solitary tract NTS, where second-order projections diverge to many CNS regions, including the VRC, RTN, cerebellum, and cortex, When increased chemoafferent neuron activity stimulates breathing, the ventilatory response is complicated by feedback interactions with CO 2
