This nerve starts from the brainstem and traverses through the base of the skull and terminates at the mouth in the mucous glands and base of the tongue. The cranial nerves consist of 12 paired nerves that arise from the brainstem.
The olfactory and optic nerves arise from the anterior portion of the brain called the cerebrum. The oculomotor and trochlear cranial nerves stem from the midbrain. As indicated in its name this nerve innervates the muscles found below hypo the tongue hence consists only of the motor component.
It provides voluntarily control over the three out of four extrinsic muscles of the tongue which. Names of 12 Cranial Nerves. Here are the names of 12 cranial nerves you can learn these names in this order.
Learn the names of these cranial nerves easily with these mnemonics. The CNs III IV VI XI and XII are mainly motor nerves and provide innervation of the skeletal muscles. 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 accessory spinal accessory. Mainly motor Cranial and Spinal Roots Located in the jugular foramen. Controls the sternocleidomastoid and trapezius muscles and overlaps with functions of the vagus nerve CN X.

The 12 pairs of CNs originate from the nose CN I the eyes CN II the inner ear CN VIII the brainstem CN III-XII and the spinal cord part of XI. CNs have sensory afferent and motor efferent functions. CN I and CN II convey sensory information.
The olfactory and optic nerves arise from the cerebrum and diencephalon respectively. The cranial nerves are numbered in order of their position from the front to the back of the brain and so they are always listed in the same order. The Olfactory nerves relay sense information from the nostrils and are vital for our sense of smell.
