- Retina
- Ultra-sensitive membrane of the inside of the back of the eye. it is here that objects are focused. images are then transmitted via the optic nerve to the vision centers in the brain where they are interpreted.
- The inside layer of the eye which is sensitive to light. detached retina. see illustration at eye in supplement (note: the plural is retinae.) comment: light enters the eye through the pupil and strikes the retina. light-sensitive cells in the retina (cones and rods) convert the light to nervous impulses. the optic nerve sends these impulses to the brain which interprets them as images. the point where the optic nerve joins the retina has no light-sensitive cells, and is known as the blind spot.
- The light sensitive inner lining of the back of the eye; the retina has two different types of cells that detect and respond to light—rods and cones. these cells that are sensitive to light are called photoreceptors. [source]
- In the eye, the tissue that senses light.
- In the eye, the tissue on back, inside surface of the eyeball, opposite the pupil, where light sensitive rods and cones sense light.
- In the eye, the tissue on back, inside surface of the eyeball, opposite the pupil, where light sensitive rods and cones sense light. see also cone; fovea centralis; iris; pupil; rod.
