Branch of glossopharyngeal nerve to carotid sinus help maintain a more consistent blood pressure) and from chemoreceptors in the carotid body (mainly monitoring blood gas PaO2 and PaCO2 levels). Hering's nerve responds to both increases and decreases in blood pressure while the baroreceptors in the aortic arch respond only to increases in blood pressure . Branch of glossopharyngeal nerve to carotid sinus The branch of glossopharyngeal nerve to the carotid sinus (Hering's nerve) is a small nerve in the neck, that innervates the carotid sinus and the carotid body. It is a branch of the glossopharyngeal nerve that runs downwards, anterior to the internal carotid artery. It
Carotid sinus with verapamil or adenosine though is still the preferred first line of treatment in a hemodynamically stable patient Carotid sinus reflex death is a potential etiology of sudden death in which manual stimulation of the carotid sinus allegedly causes strong glossopharyngeal nerve (Vagus nerve is for aortic arch baroreceptors) impulses leading to terminal cardiac arrest. Carotid sinus reflex death has been pointed out as a possible cause of death in cases of strangulation, hanging and autoerotic strangulation, but such deductions remain controversial. However, medical literature is replete with studies examining the use of carotid sinus massage as a diagnostic and
