Efferent Innervation of the Carotid Body and Carotid Sinus in the Guinea Pig
Both carotid body chemoreceptors and carotid sinus baroreceptors are influenced by efferent fibres supplied via the sinus nerve and direct sympathetic branches. These efferent fibres were subjected to a histochemical investigation to obtain more information on the possible transmitters and modulators involved in this efferent-afferent interaction.
