Retina \Ret"i*na\, n. [NL., from L. rete a net. Cf. Reticule.] (Anat.) The delicate membrane by which the back part of the globe of the eye is lined, and in which the fibers of the optic nerve terminate. See Eye.
Note: The fibers of the optic nerve and the retinal blood vessels spread out upon the front surface of the retina, while the sensory layer (called Jacob's membrane), containing the rods and cones, is on the back side, next the choroid coat.
Douglas Harper's Etymology Dictionary
late 14c., from Medieval Latin retina "the retina," probably from Vulgar Latin (tunica) *retina, literally "net-like tunic," on resemblance to the network of blood vessels at the back of the eye, and ultimately from Latin rete "net" (see reticulate (adj.)). The Vulgar Latin phrase might be Gerard of Cremona's 12c. translation of Arabic (tabaqa) shabakiyyah "netlike (layer)," itself probably a translation of Greek amphiblestroeides (khiton).
Wiktionary

Wikipedia
The retina ( , , pl. retinae, ; from Latin rēte, meaning "net") is the third and inner coat of the eye which is a light-sensitive layer of tissue. The optics of the eye create an image of the visual world on the retina (through the cornea and lens), 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 centres of the brain through the fibres of the optic nerve.
In vertebrate embryonic development, the retina and the optic nerve originate as outgrowths of the developing brain, specifically the embryonic diencephalon; thus, the retina is considered part of the central nervous system (CNS) and is actually brain tissue. It is the only part of the CNS that can be visualized non-invasively.
The retina is a layered structure with several layers of neurons interconnected by synapses. The only neurons that are directly sensitive to light are the photoreceptor cells. For vision, these are of two types: the rods and cones. Rods function mainly in dim light and provide black-and-white vision while cones support the perception of colour. A third type of photoreceptor, the photosensitive ganglion cells, is important for entrainment and reflexive responses to the brightness of light.
Neural signals from the rods and cones undergo processing by other neurons of the retina. The output takes the form of action potentials in retinal ganglion cells whose axons form the optic nerve. Several important features of visual perception can be traced to the retinal encoding and processing of light.
Retina (or More Fun Than a Vat of Love) is a ten-track album by Scottish orchestral rock band How to Swim. Produced by Gavin Thomson and the band's own Ink Wilson, the record was released on 4 October 2010 through Personal Hygiene Records.
Guest musicians include saxophonist Tom Brogan from Glasgow band The Low Miffs as well as Kimberley Moore, vocalist with Zoey Van Goey, who takes lead vocals on the track "False".
The record is the first full-length How to Swim release to not be a compilation of earlier EPs or singles.
The retina is a light-sensitive layer of tissue, lining the inner surface of the eye.
Retina may also refer to:
- Kodak Retina, a series of cameras made from 1936 to 1969
- Retina Display, brand names used by Apple Inc. for screens with a high pixel density
- Retina (or More Fun Than a Vat of Love), a 2010 album by How to Swim
Usage examples of "retina".
Holograms and retina prints given by the government of Bespin after a Rebel raid match yours 3.
Pat came to work at the Exploratorium that she found out that drifting horse shape was a bit of junk floating in the liquid in front of her retina.
He could find nothing in the cornea, nothing in the sclera, nothing in the iris, nothing in the retina, nothing in the lens of the eye, nothing in the luteous macula, nothing in the optic nerve, nothing elsewhere.
The center of the retina, called the macula, is the most active part of the eye and processes the light signals that allow us to do fine work like reading and recognizing facial detail and beauty.
The photoreceptors of your eye are part of the retina, a layer of cells at the back of your eyeball.
The photoreceptors detect light and the patterns that it forms on the retina, then sends this information to your brain via the optic nerve.
The horizon scanner chirruped, and Alae aimed the display projector at her retina.
However, meanings of signals from some types of sensory cells are necessarily position-dependent: the position of a retinal receptor relates to its position in the image projected onto the retina, the position of a receptor for touch is its actual position on the body, and the position of a receptor for sound in the organ of Corti is a function of frequency.
His exoself responded to the command, spinning his balls into hyperspheres, rebuilding his retinas as four- dimensional arrays, rewiring his visual cortex, boosting his neural model of the space around him to encompass five dimensions.
In these cases the lesions have consisted of detachment of the retina, optic atrophy, cataract, hemorrhages into the retina, and rupture of the choroid, paralysis of the oculomotor muscles, and paralysis of the optic nerve.
In retinitis pigmentosa the peripheral or extramacular portions of the retina are subject to a pigmentary degeneration that renders them insensitive to light, and patients so afflicted are consequently incapable of seeing at night as well as others.
Solar retinopathy is the fancy name for damage to the back of the eye caused when radiation from the sun is concentrated by the lens onto the retina.
Theoretically, we could virally implant a gene complex that alters the cells in your retina to give you thermographic vision.
Muller and Kolliker can be relied upon, this question is settled by recognizing that a layer of cells, continued from the retina, passes over the surface of the zonula Zinnii, but that no proper nervous element is so prolonged forward.
If the brain is to interpret images arriving at the retina of the eye, these pathways, with their compressions and expansions, have to be organized in an orderly manner - and indeed it can be shown that there is a precise topographic mapping of the retina onto the neurons of the lateral geniculate and a further mapping of these cells onto those of the visual cortex.
