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 carries impulses from the retina to the brain?
Optic Nerve!!
How are neural impulses generated?
The neural impulse is the electrical charge that goes from the nerve receptor to the brain. They are generated when the nerve receptor detects a foreign stimuli.
Part of a neuron that transmits nerve impulses toward the central nervous system?
Afferent neurons do this. Efferent do the opposite. It does not matter which system the neurons belong to i.e. Automonic vs. sympathetic. This is a general definition of the direction which nerve impulses are conducting. Afferent nerves are more commonly but less accurately known as sensory nerves.
How does the retina work?
"The optics of the eye create an image of the visual world on the retina, which serves much the same function as the film in a camera. Light striking the retina initiates a cascade of chemical and electrical events that ultimately trigger nerve impulses. These are sent to various visual centers of the brain through the fibers of the optic nerve." http://en.wikipedia.org/wiki/Retina
Which part of the brain receives impulses for sight from the eyes?
Fore Brain
Encoded information travels along the optic nerve to the?
The optic nerve transmits visual impulses from the retina to the brain.
What is the sensitive innermost layer that lines the posterior segment of the eye is known as the This structure receives nerve impulses and transmits them to the brain?
Retina
How do the cornea lens and retina aid the vision process?
Cornea: Transmits & focuses light into the eye. Lens: Focuses light rays onto the retina. Retina: Creates impulses to the brain. Thepupil is a hole located in the center of the iris of the eye that allows light to enter the retina.
What is the function of the optic nerve?
As with all nerves in the human body, the optic nerve transmits information. In this case, the optic nerve specifically transmits information from the retina of the eye to the brain for analysis and integration, resulting in the perception of "sight."
How does the optic nerve work?
The optic nerve is a group of nerve fibers that function to provide vision. The optical never works by transferring electrical impulses to the brain from a part of the eyes known as the retina.
Which part of the eye transmits visual data?
The optic nerve transmits visual date from the retina to the brain.
How does the cornea in are eye help us?
Cornea: Transmits & focuses light into the eye. Lens: Focuses light rays onto the retina. Retina: Creates impulses to the brain. Thepupil is a hole located in the center of the iris of the eye that allows light to enter the retina.
What is the optics?
It is a bundle of nerve fibers that carry electrical impulses to the brain from the retina.
What is a light-sensitive feature that receives visual images and transmits impulses to the brain?
the iris
What is the function of the nerves of the eye?
optic nerve is the one that transmits visual information from the retina to the brain.
Does eyesight have speed?
Yes. Light has a speed, electric impulses from the retina to the brain have speeds and the neurons in the brain have speeds.
The brain region receives Visual impulses?
the eye receives visual images from our surroundings, these images are received by the cones and rods which are on the retina which is found in the eye, the images are translated (by the cones and rods) and sent as impulses to the brain through the optic nerve, the brain is then able to inter-prate these impulses into images we see.
