WebDec 14, 2024 · Peripheral chemoreceptors are located in the carotid bodies and aortic bodies and are more responsive to blood gases than central chemoreceptors. PCO₂: Sensed directly and indirectly as H + by peripheral chemoreceptors Has similar effects on respiratory centers as central chemoreceptors 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.
