What is the definition of optic nerve?
Each of the second pair of cranial nerves, transmitting impulses to the brain from the retina at the back of the eye.
Which nerve transmits impulses generated by the retina to the brain?
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.
What is the name of the second cranial nerve which provides a pathway from retina to brain?
Its the Optic nerve
Cranial nerves part of what nervous system?
PNS means peripheral nervous system. CNS means central nervous system.
What is the optic nerve?
I don't know but you are getting on my nerves! Well I do know. The optic nerve is the second cranial nerve and carries information from the eyes into the brain. It does not have any control over the movement of the eyes as this comes from other nerves it only takes special sensory information on the images that the retina is receiving back to the brain to be processed. The optic nerve contains approximately 1.2 million neurons.
What is the difference between the auditory nerve and optic nerve?
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.
What is the Cranial nerve II called?
The second cranial nerve is the optic nerve.
What organ system is the optic nerve in?
Your photosensitive eyes are an extension of part of the brain surface. From clever experiments it is known that all of the surface of the brain is photo sensitive. Even some primitive organisms that do not yet have a brain, nevertheless have light sensitive receptors that are used to direct actions.
What carries sensory information from the eye to the brain?
optic....................
What nerve carries signals from the from the retina to the brain?
Occipital nerve. It is the second cranial nerve.
How does the lens of a human eye work to focus images on the retina?
When we look around we see lots of different things. right? Well have you ever wondered why this happens? Well, when we see any image at all that light comes through our eye and straight into our retina. Our retina sends this image to our optic nerves in the back of your eye which are then turned into electric impulses that are then sent to your brain. Finally receiving those electrical impulses into the actual image! I know this sounds like a very long process, but really it only happens in like a zillionth of a second! If you were looking for an answer Good luck!!
Which cranial nerves conduct the sensory and motor impulses of the eye?
The Optical nerver or the Second Cranial nerve controls and relays information absorbed through the rods and cones of the eye. Eye movements (eye muscles), however, are controlled by several other cranial nerves including the Oculomotor, Abducens, and Trochlear nerves.
