The Optic Nerve
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 auditory nerve carries electrical impulses from the ear to the brain. It connects the hair cells in the cochlea of the inner ear to the brainstem, allowing sound signals to be transmitted and interpreted by the brain.
The vestibulocochlear nerve, also known as cranial nerve VIII, is responsible for transmitting sensory information from the cochlea of the inner ear (responsible for hearing) and the semicircular canals (responsible for balance) to the brainstem.
The occipital lobe receives impulses traveling down cranial nerve 2. This nerve, known as the optic nerve, is responsible for transmitting visual information from the eye to the brain for processing.
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.
Each of the second pair of cranial nerves, transmitting impulses to the brain from the retina at the back of the eye.
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 spinal cord and the abdomen, limbs, and chest. Spinal nerves carry impulses between the spinal cord and the abdomen, limbs, and chest. Cranial nerves carry impulses between the brain and the neck and head.

Smell impulses are carried by the cranial nerve called the olfactory nerve (cranial nerve I). It is responsible for transmitting information about odors from the nose to the brain.
The auditory nerve carries auditory impulses to the brain.
Olfactory
The auditory nerve carries electrical impulses from the ear to the brain. It connects the hair cells in the cochlea of the inner ear to the brainstem, allowing sound signals to be transmitted and interpreted by the brain.
