which of the cranial nerves below is purely sensory?
333757
Cranial nerves I, II, and VIII are pure sensory nerves. Cranial nerves III, IV, VI, XI, and XII are pure motor nerves. Cranial nerves V, VII, IX, and X are mixed sensory and motor nerves. The olfactory nerve (CN I) contains special sensory neurons concerned with smell.

The numbering of the cranial nerves is based on the order in which they emerge from the brain, front to back (brainstem). The terminal nerves, olfactory nerves (I) and optic nerves (II) emerge from the cerebrum or forebrain, and the remaining ten pairs arise from the brainstem, which is the lower part of the brain.

There are two cranial nerves associated with the midbrain, the oculomotor (cranial nerve III) and the trochlear (cranial nerve IV).

The function of the cranial nerves is for the most part similar to the spinal nerves, the nerves that are associated with the spinal cord. The motor components of the cranial nerves are derived from cells that are located in the brain.

The cranial preganglionic neurons project to the cranial nerves with autonomic activity: III, VII, IX, and X. Unlike the sympathetic nervous system, the parasympathetic postganglionic neurons are located near to end-organ systems, resulting in long preganglionic axons and relatively short postganglionic axons.

The peripheral nervous system is divided into the somatic nervous system and the autonomic nervous system. In the somatic nervous system, the cranial nerves are part of the PNS with the exception of the optic nerve (cranial nerve II), along with the retina.

In higher vertebrates (reptiles, birds, mammals) there are 12 pairs of cranial nerves: olfactory (CN I), optic (CN II), oculomotor (CN III), trochlear (CN IV), trigeminal (CN V), abducent (or abducens; CN VI), facial (CN VII), vestibulocochlear (CN VIII), glossopharyngeal (CN IX), vagus (CN X), accessory (CN XI), and ...

V. The trigeminal nerve is the largest of your cranial nerves and has both sensory and motor functions.
563322
Cranial nerves are generally named according to their structure or function. For example, the olfactory nerve (I) supplies smell, and the facial nerve (VII) supplies the muscles of the face.

The sensory (also known as afferent) division of the nervous system contains nerves that come from the viscera (internal organs) and the somatic areas (muscles, tendons, ligaments, ears, eyes and skin). These nerves conduct impulses to the PNS/CNS providing information on what is happening within and outside the body.

Trigeminal nerve. The trigeminal nerve is the largest of your cranial nerves and has both sensory and motor functions.

SOMATIC NERVOUS SYSTEM (SNS) OF THE PNS (PERIPHERAL NERVOUS SYSTEM) CONSISTS OF: SENSORY NEURONS, CALLED SOMATIC SENSORY NEURONS, THAT CONVEY INFORMATION FROM SENSORY RECEPTORS IN THE SKIN, SKELETAL MUSCLES, JOINGS, AND FOR THE SPECIAL SENSES (VISION, HEARING, TASTE, AND SMELL) TO THE CNS.

The final four cranial nerves originate from the medulla oblongata: glossopharyngeal nerve (CN IX) vagus nerve (CN X) accessory nerve (CN XI)

The external ear and the outer side of the eardrum have several cranial nerves that relay information to the brain. A foreign object, such as a bug, can irritate these nerves. The insect might still be alive and may be crawling or buzzing, which could cause odd sensations in the ear.
408860
The peripheral nervous sytem comprises of cranial and spinal nerves. Ten pairs of cranial nerves run from the brain and innervate to the different parts of the body to send information. Ten spinal nerves are used to send information from extremities to the brain through the soinal cord.

The brain. The auditory nerve connects the cochlea of the inner ear directly to the auditory cortex on both sides of the brain, where sound is processed.
