However, the CNs I and II mentioned before and the vestibulocochlear nerve are purely sensory, but there are also CNs (CN V, VII, IX, X) that are both sensory and motor nerves. 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 functions of the cranial nerves are sensory, motor, or both: Sensory cranial nerves help a person to see, smell, and hear. Motor cranial nerves help control muscle movements in the head and neck.
