This essay talks about cranial nerve disorders and cranial nerve examinations. These nerves affect the connections between cranial nerve centers within the brain. Twelve pairs of cranial nerves lead directly from the brain to several parts of the head, neck, and trunk. All twelve cranial nerves are peripheral nerves. Some of the functions of cranial nerves include aiding in seeing, tasting, and hearing. Some cranial nerves help control facial muscles and regulation of glands. The symptoms of cranial nerve disorders include facial pain, dizziness, loss of hearing, paralysis, and facial twitches. These disorders affect the nerves differently, with effects such as dilated and unreactive pupils.

GENERAL INSPECTION DURING CRANIAL NERVE EXAMINATION
Some of the aspects observed during cranial nerve examinations include speech, pupillary and eyelid abnormalities, facial asymmetry, and strabismus. Speech abnormalities are indications of glossopharyngeal, while facial asymmetry suggests possible facial nerve palsy. These examinations help to determine the type of cranial nerve disorders a patient has. Healthcare professionals also observe the limbs for any abnormalities, such as spasticity and fasciculation, which suggest the presence of a neurological syndrome. These disorders affect the normal functions of cranial nerves and may require patients to use walking, hearing, or visual aids. Healthcare professionals can also prescribe medicines that help improve the functioning of cranial nerves.

FUNCTIONS AND FACTS ABOUT CRANIAL NERVES
Medical professionals who conduct cranial nerve examinations must be aware of several details regarding cranial nerves. Cranial nerves are crucial because they control body functions such as equilibrium control, eye movement, facial sensation, and hearing. Other functions of cranial nerves include aiding neck and shoulder movement, respiration, and tasting. The olfactory nerve controls the sense of smell, and the optic nerve controls all aspects of vision. The oculomotor nerve affects eyelid and eyeball movement, while the trochlear nerve controls eye movement. Depending on the particular nerve affected, people develop different forms of cranial nerve disorders. For example, damage to the trigeminal nerve affects facial sensation and chewing.
