The olfactory nerve, also known as the first cranial nerve, transports impulses for sense of smell to the brain. The olfactory nerve is capable of regeneration.
I Olfactory
the "vestibulocochlear" nerve is used for hearing. the hair cells of the cochlea and vestibular are how the nerve receives the information. The nerve is (VIII) out of the 12 cranial nerves.
Each of the second pair of cranial nerves, transmitting impulses to the brain from the retina at the back of the eye.
The second cranial nerve is the optic nerve, which tells the brain what the eye is seeing
Second cranial nerve: The second cranial nerve is the optic nerve, the nerve that connects the eye to the brain and carries the impulses formed by the retina -- the nerve layer that lines the back of the eye, senses light and creates the impulses -- to the brain which interprets them as images.The cranial nerves emerge from or enter the skull (the cranium), as opposed to the spinal nerves which emerge from the vertebral column. There are twelve cranial nerves.In terms of its embryonic development, the optic nerve is a part of the central nervous system (CNS) rather than a peripheral nerve.
The Optic Nerve
Auditory Nerve from cochleaThe eighth cranial nerve, also called as vestibulocochlear nerve, transmits the neural impulse from inner ear to brain.the cochleaThe cochlea.
The nerve that carries the signals to the brain is the ossicles
olfactory
The olfactory nerve carries impulses from odor-detecting cells to the brain.
sound waves enter the ear canal and cause the eardrum to vibrate.VIBRATIONS pass through 3 connected bones in the middle earThis motion SETS FLUID MOVING in the inner ear.Moving fluid bends thousands of delicate hair-like cells which convert the vibrations into NERVE IMPULSES.Nerve impulses are CARRIED to the brain by the auditory nerveIn the brain, these impulses are CONVERTED into what we "hear" as sound.
