Which cranial nerves provide sensory input to brainstem
nuclei?
The cranial nerves are a sequence of 12 paired nerves that come from the brain straightforwardly The first two nerves (olfactory and visual) originate from the brain, and the other ten are derived from the brain stem. It might originate from a certain portion of the brain stem (midbrain, pons, or medulla) or the interconnection of two sections.
The nomenclature of the cranial nerves depend on their function and are also named numerically in notation (I-XII). The cranial nerves count by their position on the brain stem and sequence of egress from the cranium (upper to lower, then medial to lateral) (anterior to posterior). Rising from the brainstem to the sensory root of the face nerve immediately laterally, the cranial nerve VIII -vestibulocochlear nerve has two separate sections, the balancing vestibular and the hearing cochlear. Cranial nerve VIII is only a sensory nerve and its sections run together till the brainstem reaches its nucleus. The vestibular part of the nerve gives information to the vestibular nucleus situated in the lower pons along the side of the fourth ventricle.
