WHAT DOES RETINA MEAN IN ENGLISH?

Retina

The vertebrate retina is a light-sensitive layer of tissue, lining the inner surface of the eye. 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 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, so the retina is considered part of the central nervous system 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. These are mainly of two types: the rods and cones. Rods function mainly in dim light and provide black-and-white vision, while cones support daytime vision and the perception of colour.

Definition of retina in the English dictionary

The definition of retina in the dictionary is the light-sensitive membrane forming the inner lining of the posterior wall of the eyeball, composed largely of a specialized terminal expansion of the optic nerve. Images focused here by the lens of the eye are transmitted to the brain as nerve impulses.

6 QUOTES WITH «RETINA»

Famous quotes and sentences with the word retina.

1

Aubrey de Grey

In the eye, there is a type of junk that accumulates in the back of the retina that eventually causes us to go blind. It's called age-related macular degeneration.

2

Johannes P. Muller

The cooperation of the two retina in one field of vision, whatever is its cause, must rather be the source of all the ideas to which single or double vision may give rise.

3

Johannes P. Muller

It is exceedingly improbable that the identical action of the corresponding parts of the two retina is the result of a certain habituation, or of the influence of the mind.

4

John Singer Sargent

'Impressionism' was the name given to a certain form of observation when Monet, not content with using his eyes to see what things were or what they looked like as everybody had done before him, turned his attention to noting what took place on his own retina (as an oculist would test his own vision).

5

Sebastian Seung

If we can map the retina, that will help us understand how it functions in vision, as well as devise new ways of repairing its malfunctions. And if we can really figure out the retina, perhaps we will have a shot at figuring out the vastly more complicated brain.

6

Bill Viola

If you look at landscape in historical terms, you realize that most of the time we have been on Earth as a species, what has fallen on our retina is landscape, not images of buildings and cars and street lights.
