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.

Central Chemoreceptors - an overview ScienceDirect Topics
Peripheral chemoreceptors work in concert with central chemoreceptors, which also monitor blood CO 2 but do it in the cerebrospinal fluid surrounding the brain. A high concentration of central chemoreceptors is found in the ventral medulla , the brainstem area that receives input from peripheral … See more Peripheral chemoreceptors (of the carotid and aortic bodies) are so named because they are sensory extensions of the peripheral nervous system into blood vessels where they detect changes in chemical … See more • Central chemoreceptors • Chemoreceptors • Control of respiration See more • Nosek, Thomas M.
