Several clusters of chemoreceptive and supporting cells associated with blood vessels and nerves (especially the glossopharyngeal and vagus). The nonchromaffin paraganglia sense pH, carbon dioxide, and oxygen concentrations in the blood and participate in respiratory, and perhaps circulatory, control. They include the CAROTID BODY; AORTIC BODIES; the GLOMUS JUGULARE; and the GLOMUS TYMPANICUM.
