Diagram of the retina. The total retina is a circular disc of between 30 and 40 mm in diameter Polyak 1941. A schematic section through the human eye with a schematic enlargement of the retina. The retina is approximately 05 mm thick and lines the back of the eye.

You might get help from the retina histology labeled diagram to understand these cells and layers. Outer plexiform layer of retina The outer plexiform layer of retina is a synaptic layer that is formed by the axon fibers of rods and cones cells with dendrite. Human retina measures 32 mm from ora to ora along the horizontal meridian and t he total surface area of the retina in each eye is approximately 1100 square mm.

2 The average thickness of retina is 200 micrometers it is slightly thicker near optic nerve head and near the macula and gradually thins out at the ora serrata and fovea. 3 Broadly the retinal surface can be divided into the following. The retina is a thin layer of tissue that lines the back of the eye on the inside.

It is located near the optic nerve. The purpose of the retina is to receive light that the lens has focused. The retina is the sensory membrane that lines the inner surface of the back of the eyeball.

Its composed of several layers including one that contains specialized cells called photoreceptors. There are two types of photoreceptor cells in the human eye rods and cones. Rod photoreceptors detect motion provide black-and.

Despite its peripheral location the retina or neural portion of the eye is actually part of the central nervous system. During development the retina forms as an outpocketing of the diencephalon called the optic vesicle which undergoes invagination to form the optic cup Figure 113. See also Chapter 22.

The inner wall of the optic cup gives rise to the retina while the outer wall gives. Anatomy of Retina By DrAshok Kumar Valuroutu. The retina is a thin semitransparent multilayered sheet of neural tissue that lines the inner aspect of the posterior two-thirds of the wall of the globe.

Thin delicate layer of nervous tissue Surface area of 266 mm2 Extends from optic disc to ora serrata. Grosss anatomy Three distinct regions of retina. 1optic disc 2macula lutea 3peripheral retina retina extends from optic disc to ora serrata Surface area266sqmm 4.

Optic disc Pale pink in colour. Well defined circular area Diameter. 15mm All the retina layers terminate hereexcept the nerve fibre which pass through the lamina cribrosa.

Each layer of cells in this tissue serves a specific purpose. As we prepare for Age-Related Macular Degeneration Awareness Month in February a closer look at the layers of the retina and their function. Layers of the Retina.

Choroid This is made up of a layer of blood vessels that supply oxygen and nutrients to the retina. Defect in the CHM gene can cause choroideremia leaky blood vessels can. Browse 162 retina diagram stock photos and images available or start a new search to explore more stock photos and images.

Detailed wiring diagram for the retina that is a quantitative map of all its excita-tory and inhibitory synaptic connec-tions12. Propelling this effort has been a faith that the diagram would ultimately make functional sensethat we would be able to read the diagram of a neural cir-cuit just as we do for an electronic circuit. The retina is a light-sensitive layer that lines the back of the eye.

It is only 02 mm thick and is about the size of a silver dollar. The retina is made up of 200 million neurons many of which are photoreceptors. Photoreceptors absorb light and then convert and transmit those signals through the optic nerve to the brain.

Light enters the retina on the side containing the optic nerves and travels through all the layer before reaching the receptors. To see this in action.

The retina is a thin layer of tissue that lines the inside of the back of the eye and is like the film in the back of a camera. When light hits the retina a picture travels through the optic nerve to the brain. The optic nerve is a thick bundle of nerve fibers.

The retina is the light-sensitive tissue at the back of the eye. The retina converts light into electrical impulses that are sent to the brain through the optic nerve. The retina is the light-sensitive tissue at the back of the eye.

The retina converts light into electrical impulses that are sent to the brain through the optic nerve. The vitreous gel is a transparent colorless mass that fills the rear two-thirds of the eyeball between the lens and the retina. Diabetes and Healthy Eyes Toolkit.

Schematic diagram of the macula lutea of the retina showing perifovea parafovea fovea and clinical macula The macula is an oval-shaped pigmented area near the center of the retina of the human eye and other animal eyes. Marc and his colleagues have led the way in documenting the retinas connectome which he referred to as the complete wiring diagram for the retina The size of the human retinas connectome or the number of pathways is mind-blowingly large. The retina is the light-sensitive tissue that lines the inside of the eye.

The retina functions in a manner similar to film in a camera. The optical elements within the eye focus an image onto the retina of the eye initiating a series of chemical and electrical events within the retina. Nerve fibers within the retina send electrical signals to.

Central retinal artery Arteria centralis retinae The central retinal artery Zinns artery is a branch of the ophthalmic arteryIt provides arterial supply to the inner surface of the eye. Specifically this artery provides the majority of the retinal arterial supply except for the layer of cones and rods.
