The structure of the eye that contains the visual receptors and several layers of neurons farther along the pathway to the brain.
The inside layer of the eye which is sensitive to light.
Light-sensitive layer at the back of the eye.
Multilayered light-sensitive layer of the eye that receives images of objects and transmits visual impulses through the optic nerve to the brain for interpretation. The outer part of the retina, next to the choroid, contains the pigment rhodopsin; the inner layers, continuing to the vitreous humor, contain rods and cones (light-sensitive nerve cells) and their associated ganglia and fibers.
Membrane lining the posterior cavity of the eye that contains rods and cones.
The light-sensitive membrane that forms the inner layer of the back of the eye and contains the nerve receptors for vision. Light that has passed into the eye reaches the retina as an inverted image. The retina is a complex structure, a ten-layered membrane lined with two kinds of light-sensitive cells. Rod cells—so-called because of their shape—perceive shape and movement. Cone cells are sensitive to both light and color and have a role in visual acuity, or sharpness of perception. Because the retina has many more rods than cones, the eye can perceive light in darkness, but it sees color best in bright light. Rods and cones—also called photoreceptors— respond to light focused on the retina by translating the stimulus into electrochemical nerve signals.
The light-sensitive layer that lines the interior of the eye. The outer part of the retina, next to the choroid, is pigmented to prevent the passage of light. The inner part, next to the cavity of the eyeball, contains rods and cones (light-sensitive cells) and their associated nerve fibers. A large number of cones is concentrated in a depression in the retina at the back of the eyeball called the fovea.
The innermost layer of the eye, which receives images transmitted through the lens and contains the receptors for vision, the rods and cones.
The light-sensitive inner layer of the eye, which receives images formed by the lens and transmits nerve signals through the optic nerve to the brain.
The innermost layer of the eye; the light-sensing part of the eye.
Situated at the rear of the eye, there exists a photosensitive tissue responsible for capturing visual images and converting them into electrical signals, which are then transmitted to the brain through the optic nerve.
The light-responsive layer covering the inner rear portion of the eye, where images are projected by the cornea (the clear dome shaping the front of the eye) and the lens (the eye component that handles focusing). Within the retina are specialized nerve cells known as rods and cones, which transform light energy into nerve signals. These signals traverse from the rods and cones through additional retinal cells and subsequently along the optic nerve to the brain.
The rods possess high sensitivity and react to faint light, while the cones handle color perception by generating signals of varying intensity based on the light’s hue. Situated close to the retina’s center is the fovea, a region crucial for precise vision due to its dense assembly of light-sensitive cells.
The retina is the light-sensitive layer at the back of the eye that captures visual information. It extends from the optic nerve and consists of eight layers, with seven being neural and one being pigmented. The central part of the retina aids in clear vision during bright conditions, while the outer region contains special structures for low-light vision. This peripheral area enhances side vision in the dark, making it clearer than direct vision in low light.
