Auditory nerve is eighth cranial nerve. It is called as vestibulocochlear nerve. It is the nerve to meant for hearing and balancing your body. The optic nerve is second cranial nerve. It carries sensory signals from your eye to the brain. It arises from the retina of the eye.
Your eyes are connected to your brain by optic nerves, not auditory nerves. Optic nerves transmit visual information from the eyes to the brain for processing, while auditory nerves transmit information related to hearing from the ears to the brain.
The optic nerve is associated with sight, transmitting visual information from the eye to the brain. The vestibulocochlear nerve is associated with hearing and balance, transmitting auditory and vestibular information from the inner ear to the brain.
The junction of the retina and optic nerve is called the optic disc or optic nerve head. This is where the optic nerve exits the eye and carries visual information from the retina to the brain. The optic disc is also known as the blind spot because it lacks photoreceptor cells and cannot detect light.
The question is asking what three cranial nerves are purely sensory in their function. Some relevant terms here are olfactory, optic, and auditory or vestibucochlear or acoustic nerves. The only three cranial nerves that are pure sensory in function are cranial nerve #1 : the olfactory nerve (smell), cranial nerve #2 : the optic nerve (sight), and cranial nerve #8 : the auditory/vestibucochlear/acoustic nerve (hearing).
Occipital nerve. It is the second cranial nerve.
Point where optic nerve enters eyeball is the optic disc.
The optic nerve leaves the eye at the back of the eyeball, where it connects to the retina. This point is known as the optic disc or optic nerve head.
Another name for the optic nerve head is the optic disc.
optic nerve
The optic nerve can be identified with the sense of sight.
No, the optic nerve does not pass through the foramen ovale. The optic nerve is a cranial nerve that passes through the optic canal, located within the sphenoid bone, to connect the eye to the brain. The foramen ovale is a separate opening in the skull that allows passage of the mandibular nerve.
