      HERING’S NERVE AND VASOMOTOR NERVOUS SYSTEM OF THE CAROTID ARTERY (Abstract): The aim of present research was to demonstrate, morphologically, the role that glossopharyngeal nerve carotic branches have in sinocarotic baroreceptors and chemoreceptors innervation, known in literature under the name of „Hering’s nerve”. Hering’s nerve provides innervation for the two components of the sinocarotid region, the carotid sinus and glomus. The first one is the baroreceptor of the internal carotid artery, located in its adventiceal layer, the second one located at the bifurcation of the common carotid artery, having a role in detecting blood composition changes. Hering’s nerve is a collateral branch of the glossopharyngeal nerve, participating along the vagus nerve to the sensory innervation of the carotid sinus and glomus. Also participates in forming the nervous intercarotid plexus, together with carotid branches from the vagus nerve, and with postganglionic nervous fibers from the superior cervical sympathetic ganglion.
Key words: HERING’S NERVE, GLOSSOPHARYNGEAL NERVE, CAROTID SINUS, CAROTID GLOMUS
