vestibulocochlear nerve: Also known as the auditory vestibular nerve, this is the eighth of twelve cranial nerves, and it is responsible for transmitting sound and equilibrium (balance) information from the inner ear to the brain.

Which cranial nerve is the auditory nerve?

Cranial nerve VIII brings sound and information about one's position and movement in space into the brain. The auditory and vestibular systems subserve several functions basic to clinical medicine and to psychiatry.

Which cranial nerve carries information about hearing from the inner ear to the brain?

Coming from the inner ear and running to the brain is the eighth cranial nerve, the auditory nerve. This nerve carries both balance and hearing information to the brain.

Which cranial nerve is the auditory nerve group of answer choices?

vestibulocochlear nerve, also called Auditory Nerve, Acoustic Nerve, or Eighth Cranial Nerve, nerve in the human ear, serving the organs of equilibrium and of hearing.

Where is the auditory nerve?

The cochlear nerve, also known as the acoustic or auditory nerve, is the cranial nerve responsible for hearing. It travels from the inner ear to the brainstem and out through a bone located on the side of the skull called the temporal bone.

What is 7th cranial nerve?

The facial nerve is the seventh cranial nerve (CN VII). ... The facial nerve provides motor innervation of facial muscles that are responsible for facial expression, parasympathetic innervation of the glands of the oral cavity and the lacrimal gland, and sensory innervation of the anterior two-thirds of the tongue.

Which of the cranial nerves transmits from the cochlea and semicircular canals to the brain?

Inferior view of the human brain, with the cranial nerves labelled. The vestibulocochlear nerve (auditory vestibular nerve), known as the eighth cranial nerve, transmits sound and equilibrium (balance) information from the inner ear to the brain.

What is the auditory canal in the ear?

external auditory canal, also called external auditory meatus, or external acoustic meatus, passageway that leads from the outside of the head to the tympanic membrane, or eardrum membrane, of each ear. The structure of the external auditory canal is the same in all mammals.

Which part of the brain receive the impulses from the auditory nerve?

Auditory nerves and the brain

Nerve impulses are transmitted from the ear to the brain via the auditory nerves, one of the several sensory nerves that exists in the group of nerves known as cranial nerves. The auditory nerves connect the nerve impulses of the ears to the upper "temporal lobe" of the "cerebral cortex".

Which cranial nerve is responsible for bringing auditory and orientation information to the brain?

Which cranial nerve is responsible for bringing auditory and orientation information to the brain? Explanation: Cranial nerve VIII is also called the vestibulocochlear nerve. It is a sensory nerve responsible for bringing information from the cochlea and semicircular canals to the brain.

What nerve is responsible for rotating the head?

Cranial nerve XI is responsible for tilting and rotating the head, elevating the shoulders, and adducting the scapula. Most of the fibers of the accessory nerve originate in neurons situated in the upper spinal cord.

What does the vagus nerve do?

The vagus nerve is responsible for the regulation of internal organ functions, such as digestion, heart rate, and respiratory rate, as well as vasomotor activity, and certain reflex actions, such as coughing, sneezing, swallowing, and vomiting (17).

What part of the brain is responsible for auditory processing?

The auditory cortex is found in the temporal lobe. Most of it is hidden from view, buried deep within a fissure called the lateral sulcus. Some auditory cortex is visible on the external surface the brain, however, as it extends to a gyrus called the superior temporal gyrus.

What nerves are connected to hearing?

The cochlear nerve, also known as the acoustic nerve, is the sensory nerve that transfers auditory information from the cochlea (auditory area of the inner ear) to the brain. It is one of the many pieces that make up the auditory system, which enables effective hearing.

Where is the auditory cortex located in the brain?

The primary auditory cortex (A1) is located on the superior temporal gyrus in the temporal lobe and receives point-to-point input from the ventral division of the medial geniculate complex; thus, it contains a precise tonotopic map.

Where are the auditory receptor cells located?

In mammals, the auditory hair cells are located within the spiral organ of Corti on the thin basilar membrane in the cochlea of the inner ear. They derive their name from the tufts of stereocilia called hair bundles that protrude from the apical surface of the cell into the fluid-filled cochlear duct.

How does sound enter the ear?

Sound waves entering the ear travel through the external auditory canal before striking the eardrum and causing it to vibrate. The eardrum is connected to the malleus, one of three small bones of the middle ear. Also called the hammer, it transmits sound vibrations to the incus, which passes them to the stapes.

What is the function of the auditory tube?

Auditory tube: The tube that runs from the middle ear to the pharynx, also known as the Eustachian tube. The function of this tube is to protect, aerate and drain the middle ear (and mastoid). Occlusion of the Eustachian tube leads to the development of middle ear inflammation (otitis media).

Which cranial nerve carries the sense of hearing and equilibrium?

The vestibulocochlear nerve is responsible for the sense of hearing and balance (body position sense). The glossopharyngeal nerve enervates muscles involved in swallowing and taste.

What are the auditory ossicles?

The auditory ossicles (malleus, incus, and stapes) play a key role in this function. The malleus connects to the tympanic membrane transferring auditory oscillations to the incus and then the stapes. The stapes connects to the oval window allowing for mechanical energy to be transferred to the fluid-filled inner ear.

Which of the following cranial nerves carries only motor information?

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 optic nerve (CN II) contains sensory neurons dedicated to vision.

What are cranial nerves 9 and 10?

CRANIAL NERVE 9 (GLOSSOPHARYNGEAL) AND CRANIAL NERVE 10 (VAGUS) CNs 9 and 10 work together to supply the musculature of the pharynx (mostly supplied by CN 10) and transmit visceral afferent information from vascular baroreceptors, and each nerve also has additional individual functions listed below.

What is the name of the tenth cranial nerve?

The vagus nerve (cranial nerve [CN] X) is the longest cranial nerve in the body, containing both motor and sensory functions in both the afferent and efferent regards.

What is the lingual nerve?

The lingual nerve is one of the sensory branches of the mandibular division of the trigeminal nerve. [5] It contains general somatic afferent nerve fibers and, after chorda tympani joins it, also carries general visceral efferent nerve fibers and special visceral afferent fibers.
