The cranial nerve exam is a type of neurological examination.It is used to identify problems with the cranial nerves by physical examination.It has nine components. Each test is designed to assess the status of one or more of the twelve cranial nerves (I-XII).
A neurological examination is the assessment of sensory neuron and motor responses, especially reflexes, to determine whether the nervous system is impaired. This typically includes a physical examination and a review of the patient's medical history, [1] but not deeper investigation such as neuroimaging.
Lateral to CN VII (cerebellopontine angle) Located in the internal acoustic canal. Mediates sensation of sound, rotation, and gravity (essential for balance and movement). More specifically, the vestibular branch carries impulses for equilibrium and the cochlear branch carries impulses for hearing. IX Glossopharyngeal: Both sensory and motor ...
CN XII is a nerve with a sole motor function. The nerve arises from the hypoglossal nucleus in the medulla [ 1 ] [ 2 ] as a number of small rootlets, pass through the hypoglossal canal and down through the neck, and eventually passes up again over the tongue muscles it supplies into the tongue.

Cranial nerves are the nerves that emerge directly from the brain (including the brainstem), of which there are conventionally considered twelve pairs.Cranial nerves relay information between the brain and parts of the body, primarily to and from regions of the head and neck, including the special senses of vision, taste, smell, and hearing.
The optic nerve has been classified as the second of twelve paired cranial nerves, but it is technically a myelinated tract of the central nervous system, rather than a classical nerve of the peripheral nervous system because it is derived from an out-pouching of the diencephalon (optic stalks) during embryonic development.
Pupil reaction to light is important because it shows an intact retina, and cranial nerve number 2 (CN II) If pupils are reactive to light, then that also indicates that the cranial nerve number 3 (CN III) (or at least its parasympathetic fibers) are intact.
