Difference between Auditory system and Cranial nerves

Auditory system vs. Cranial nerves

The auditory system is the sensory system for the sense of hearing. Cranial nerves are the nerves that emerge directly from the brain (including the brainstem), of which there are conventionally considered twelve pairs.

Axon

An axon (from Greek ἄξων áxōn, axis) or nerve fiber (or nerve fibre: see spelling differences) is a long, slender projection of a nerve cell, or neuron, in vertebrates, that typically conducts electrical impulses known as action potentials away from the nerve cell body.

Brainstem

The brainstem (or brain stem) is the stalk-like part of the brain that connects the forebrain (the cerebrum and diencephalon) with the spinal cord.

Cochlea

The cochlea is the part of the inner ear involved in hearing.

Cochlear nerve

The cochlear nerve (also auditory nerve or acoustic nerve) is one of two parts of the vestibulocochlear nerve, a cranial nerve present in amniotes, the other part being the vestibular nerve.

Frontal lobe

The frontal lobe is the largest of the four major lobes of the brain in mammals, and is located at the front of each cerebral hemisphere (in front of the parietal lobe and the temporal lobe).

Hearing

Hearing, or auditory perception, is the ability to perceive sounds through an organ, such as an ear, by detecting vibrations as periodic changes in the pressure of a surrounding medium.

Inner ear

The inner ear (internal ear, auris interna) is the innermost part of the vertebrate ear.

Midbrain

The midbrain or mesencephalon is the rostral-most portion of the brainstem connecting the diencephalon and cerebrum with the pons. It consists of the cerebral peduncles, tegmentum, and tectum.

Pons

The pons (pontes; from Latin pons, "bridge", from Proto-Indo-European *pónteh₁s, “path, road”, from *pent-, “path”. Cognate with Sanskrit पन्था, pánthā-) is part of the brainstem that in humans and other mammals, lies inferior to the midbrain, superior to the medulla oblongata and anterior to the cerebellum.

Stapedius muscle

The stapedius is the smallest skeletal muscle in the human body.

Vertebrate

Vertebrates are deuterostomal animals with bony or cartilaginous axial endoskeleton — known as the vertebral column, spine or backbone — around and along the spinal cord, including all fish, amphibians, reptiles, birds and mammals.

Vestibular nerve

The vestibular nerve is one of the two branches of the vestibulocochlear nerve (the cochlear nerve being the other).

Vestibulocochlear nerve

The vestibulocochlear nerve or auditory vestibular nerve, also known as the eighth cranial nerve, cranial nerve VIII, or simply CN VIII, is a cranial nerve that transmits sound and equilibrium (balance) information from the inner ear to the brain.
