What is the examination of the cerebral nerve? To check the cerebral nerve, we mainly do physical examination of the nervous system: first, for example, when checking the optic nerve, we mainly use a visual acuity chart to check the patient’s visual acuity; second, when checking the olfactory nerve, we mainly use a test tube with a non-stimulating liquid and let the patient smell it to check the patient’s olfactory nerve; third, the motoneurotic, talipes and abducens nerves, mainly by checking the patient’s eye movement to check The fourth one is the facial nerve, where the patient can open the mouth to check whether the facial lines are symmetrical; the fifth one is the hypoglossal nerve, where the patient can extend the tongue to find out whether there is any tongue deviation; the sixth one is the paraglossal nerve, where the patient can shrug or turn the head to find out whether the paraglossal nerve is involved; the seventh one is the glossopharyngeal vagus nerve. The seventh one is the linguopharyngeal vagus nerve, which is checked by asking the patient to speak to see if there is any slurring of words or if there is any choking of water. Therefore, the general examination of the cerebral nerve is mainly to do a specialized physical examination of the nervous system to check.
