WebThe peripheral chemoreceptors are located in the carotid (carotid sinus) and aortic bodies (aortic arch). The carotid bodies respond to arterial hypoxia by increasing the firing rate from the carotid sinus nerve. WebMay 14, 2007 · Arterial chemoreceptors located in the aortic and carotid bodies (CBs) respond to hypoxemia and hypercapnia. Because central chemoreceptors also respond to hypercapnia, hypoxia is typically used as a specific stimulus to arterial chemoreceptors.

WebCentral chemoreceptors and sympathetic vasomotor outflow WebThe peripheral chemoreceptors are found in carotid bodies on the external carotid arteries near their bifurcation with the internal carotids. Afferent nerve fibers from the carotid bodies join with the sinus nerve before entering the glossopharyngeal nerve (cranial nerve IX) and travelling up to the nucleus tractus solitarius (NTS) in the medulla.

WebNow, the peripheral chemoreceptors are so named because they live outside the brain.
