The retina is a thin tissue at the back of the eye that contains several cell types that are similar to brain cells since they are all neurons The cell types include photoreceptor neurons (rods and cones) and other types of neurons The photoreceptor cells of the retina absorb light and convert this light to electrical signals The electrical signals are transferred from the photoreceptors to secondary neurons which then send the electrical signals to the visual cortex region of the brain for interpretation The brain and retina constitute the Central Nervous System of the body
Thin tissue in the back of the eye that receives an image formed by the lens and converts it to electrical impulses carried by the optic nerve to the brain
a delicate, multi-layered, light-sensitive membrane lining the inner eyeball and connected by the optic nerve to the brain It is composed of many layers including one containing the rods and cones, and functions as the immediate instrument of vision by receiving the image formed by the lens and converting it into chemical and nervous signals which reach the brain by way of the optic nerve Submitted by Jeffrey S Fox, foxjeff1@pilot msu edu rhodopsin Rhodopsin is a retinal photosensitive protein found in higher organisms, like mammals It is a lot like bacteriorhodopsin, except that's found in bacteria and slightly different in structure Submitted by Greg Brown, gbrown@artoo gisd k12 mi us
The light-sensitive layer of nerve cells (rods and cones) that lines the back of the eyeball It sends visual impulses through the optic nerve to the brain The macula is in the center of the retina and is made up of cones
a layer of fine sensory tissue that lines the inside wall of the eye The retina acts like the film in a camera to capture images, transforms the images into electrical signals, and sends the signals to the brain
the light-sensitive nerve layer that lines the back of the eye The retina sense light and creates impulses that are sent through the optic nerve to the brain
The nerve tissue that lives at the back of the eye, similar to the film in a camera, which takes the image you are looking at and transmits it to the brain through the optic nerve This area is nourished by a web of very fine blood vessels The layers of cells in the back of the eye that are responsible for sensing light and transmitting light- induced signals to the brain
The light sensitive layer of cells (rods and cones) on the inner back surface of the eye that converts light images into nervous impulses sent along the optic nerve for transmission to the brain
—A membrane lining the inside of the back of the eye that contains light-sensitive nerve cells that convert focused light into nerve impulses, making vision possible
The thin lining at the back of the eye that converts images from the eye's optical system into electronical impulses sent along the optic nerve for transmission to the brain
the posterior inside surface of the eye, which receives a light image refracted through the cornea and lens, and transmits it to the brain via the optic nerve
The sensory lining (inner coat) of the eyeball which receives images that have been focused by the lens Photoreceptor cells in the retina transform light energy into chemical energy Nerves connected to the photoreceptor cells transmit information via the optic nerve to the brain
Your retina is the area at the back of your eye. It receives the image that you see and then sends the image to your brain. the area at the back of your eye that receives light and sends an image of what you see to your brain (probably from rete ). Layer of nerve tissue covering the back two-thirds of the eyeball. Light focused onto the retina by the lens of the eye stimulates two types of light-sensitive cells: rods, which are sensitive to low light levels, and cones, which provide detailed vision and colour perception. Chemical changes in these cells trigger nerve impulses, which are assembled by complex connections among retinal nerves into a pattern to be carried through the optic nerve to the visual centres of the brain. Disorders affecting the retina or the macula in its centre decrease vision and can cause blindness. See also detached retina; macular degeneration
Located at the back of the eye, the retina's photosensitive cells convert light images into electrical impulses for the optic nerve The optic nerve sends those impulses to the visual part of the brain, where they are interpreted into what we know as "sight"
A layer of cells at the back of the eye which are sensitive to light and upon which the image formed by the lens is focused The image is then carried to the brain by the optic nerve
