Common vagal maneuvers include carotid sinus massage (CSM), Valsalva Stimulation of the cornea causes both eyes to blink (trigeminal [CN V] primary afferent and facial [CN VII] efferent). The accommodation reflex (or accommodation-convergence reflex) is a reflex action of the eye, in response to focusing on a near object, then looking at a distant object (and vice versa), comprising coordinated changes in vergence, lens shape (accommodation) and pupil size. the center is located in the pons of the brainstem. texas flower farm. Vomiting (also known as emesis and throwing up) is the involuntary, forceful expulsion of the contents of one's stomach through the mouth and sometimes the nose.. Vomiting can be the result of ailments like food poisoning, gastroenteritis, pregnancy, motion sickness, or hangover; or it can be an after effect of diseases such as brain tumors, elevated intracranial pressure, or Corneal Reflex. Stimulation of the vagus nerve in the cervix uteri (as in some medical procedures) can lead to a vasovagal response. Vomiting is dangerous if gastric content enters the respiratory tract.Under normal circumstances the gag reflex and coughing prevent this from occurring; however, these protective reflexes are compromised in persons who are under the influence of certain substances (including alcohol) or even mildly anesthetized.The individual may choke and asphyxiate or develop The corneal reflex should also be examined as the sensory supply to the cornea is from this nerve. gag reflex afferent and efferent. The brainstem (or brain stem) is the posterior stalk-like part of the brain that connects the cerebrum with the spinal cord. natshotfirst. The reflex is mediated by: the nasociliary branch of the ophthalmic branch (V 1) of the trigeminal nerve (CN V) sensing the stimulus on the cornea only (afferent fiber). Direct pupillary reflex (afferent CN II, efferent CN III): Shine a light into the pupil and observe constriction of that pupil. Most reflexes have several synapses in the reflex arc.
