Taste Buds: Small sensory organs which contain gustatory receptor cells, basal cells, and supporting cells. Taste buds in humans are found in the epithelia of the tongue, palate, and pharynx. They are innervated by the Chorda tympani nerve (a branch of the facial nerve) and the Glossopharyngeal nerve.

The cranial nerve (CN) examination follows the mental status evaluation in a neurological exam. However, the examination of the cranial nerves begins with observations made upon greeting the patient. For example, weakness of the facial muscles that are innervated by the cranial nerve VII can be readily apparent during the first encounter with the patient. Cranial nerve VII, the Facial nerve, also has sensory branches, which innervate the taste buds on the anterior two-thirds of the tongue and the medial aspect of the external auditory canal. Therefore, finding ipsilateral taste dysfunction in the patient with facial weakness confirms the involvement of CN VII. In addition, knowledge of the neuroanatomy helps the clinician to localize level of the lesion: unilateral weakness of the lower facial muscles suggests a supranuclear lesion on the opposite side, while lesions involving the nuclear or infranuclear portion of the facial nerve, manifest with an ipsilateral paralysis of all the facial muscles on the involved side. Cranial nerve VIII, the Acoustic nerve, has two divisions: the hearing (cochlear) division, and the vestibular division, which innervates
