Arose from midbrain, relay at ciliary ganglion and supplies the iris and muscles of the eye.
Optic Nerve (Cr. N. II)
When taste buds are stimulated they can produce 4 different sensations (sweet, salty, bitter, sour). These nervous impulses are carried to the brain by the facial nerve (cranial nerve VII)from the anterior 2/3 of the tongue and by the glossopharyngeal (cranial nerve IX) from the posterior 1/3 of the tongue.
Facial nerve Glossopharyngeal nerve Vagus nerve
The two cranial nerves that must be functional for the pupillary light reflex to occur are cranial nerve II (optic nerve) for the afferent pathway (carrying the visual information from the retina to the brain) and cranial nerve III (oculomotor nerve) for the efferent pathway (carrying the motor response to constrict the pupil).
what does ninth cranial nerve control? glossopharyngeal nerve is a mixed nerve, it has sensory and motor part. the sensory is at the poserior 1/3 of the tongue. It also is part of the pharyngeal plexus. (9,10,11) The motor part of the nerve ONLY supply the stylopharyngeus muscle!
If the light is shining directly into one eye, then the pupil in that eye will constrict (a direct response), but so will the pupil in the non-illuminated eye (a consensual response). This reflex involves two cranial nerves: the optic nerve, which senses the light, and the oculomotor nerve, which constricts both pupils.
3, 7, 9 and 10 (lll, Vll, lX and X) for sure. Two sources included 5=V. Two sources did not. You might want to leave V out.
Cranial nerve #2 - optic nerve - special sensory for vision Cranial nerve #3 - occulomotor nerve - motor for extraoccular muscles & parasympathetic to ciliary ganglion Cranial nerve #4 - trochlear nerve - motor for extraoccular muscle (superior oblique) Cranial nerve #6 - abduscens nerve - motor for extraoccular muscle (lateral rectus)
Brances of the Facial (VII), Glossopharyngeal (IX), and Vagus (X) cranial nerves carry information about taste
The levator palpebrae muscle is primarily responsible for opening the eyelids, it is innervated by cranial nerve 3 (occulomotor nerve). Raising the eyebrows, which will also open the eyes wider and may be what you are asking about, is done by occipitofrontalis. This muscle is innervated by cranial nerve 7 (facial nerve).
Eye movement is controlled by cranial nerves III, IV, and VI (Oculomotor, Trohlear, and Abducens, respectively). CN III innervates most of the muscles of the eye and is responsible for most eye movements.
