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.
The carotid branch of the glossopharyngeal nerve (carotid sinus nerve or Hering's nerve) is a small branch of the glossopharyngeal nerve (cranial nerve IX) ...
Baroreflex activation is distinct from vagal stimulation. [8] [9] Electrical stimulation of the external surfaces of the carotid sinus activates baroreceptors believed to be in the adventitia of the artery. This stimulates an afferent limb which activates central nervous system pathways that in turn exert two different but synergistic autonomic ...
Carotid sinus massage or Czermak–Hering test; Cold water immersion (diving reflex) Eyeball pressure (also known as the oculocardiac reflex or Aschner-Dagnini reflex) Other less clinically useful physical maneuvers that elicit a similar autonomic response through stimulation of the vagus nerve include: Coughing; Gagging and/or vomiting; Breath ...
Patients with a common sleep disorder have been fitted with an app-controlled device that zaps the nerves in the tongue to help them breathe overnight in a UK first. The technology could spell the ...
The carotid body is a small cluster of peripheral chemoreceptor cells and supporting sustentacular cells situated at the bifurcation of each common carotid artery in its tunica externa. [ 1 ] [ 2 ] The carotid body detects changes in the composition of arterial blood flowing through it, mainly the partial pressure of arterial oxygen , but also ...
Signals from the carotid baroreceptors are sent via the glossopharyngeal nerve (cranial nerve IX). Signals from the aortic baroreceptors travel through the vagus nerve ( cranial nerve X ). [ 8 ] Carotid sinus baroreceptors are responsive to both increases or decreases in arterial pressure, while aortic arch baroreceptors are only responsive to ...
The type-I cells transduce the signals from the bloodstream and are innervated by afferent nerve fibers leading back to (in the carotid body) the carotid sinus nerve and then on to the glossopharyngeal nerve and medulla of the brainstem. The aortic body, by contrast, is connected to the medulla via the vagus nerve. [3]
