Anatomy Of The Retina

It is mostly made up of blood vessels. Retina The nerve layer lining the back of the eye.

How The Retina Works Detailed Illustration Eye Anatomy The Retina Eye Health

The existence of the internal and external blood-retinal barriers and intra-retinal junctions reflects the fineness of regulation of the retinal exchanges with the circulation and within the retina itself.

Anatomy of the retina. These both further subdivide into temporal and nasal terminal arterioles resulting in four terminal arterioles. The retina is approximately 05 mm thick and lines the back of the eye. The retina is a thin layer of tissue that lines the back of the eye on the inside.

The pupil is black because the light that is allowed into the eye is absorbed in the retina. Anatomy and Physiology of the Retina Associate Professor Trevor Sherwin Department of Ophthalmology University of Auckland. The whitish circle is the nerve that connects the retina to the brain.

The macula is located in the central part of the retina and has the highest concentration of cones. 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. The transparent structure inside the eye that focuses light rays onto the retina.

The red curving structures are blood vessels which enter the retina through the nerve. They function best in bright light and are essential for acute vision receiving a sharp accurate image. These cells can be divided into a.

A radial section of a portion of t. The human retina contains between six and seven million cones. The retina is made up of 200 million neurons many of which are photoreceptors.

The optic nerve contains the ganglion cell axons running to the brain and additionally incoming blood vessels that open into the retina to vascularize the retinal layers and neurons Fig. The optic nerve contains the ganglion cell axons running to the brain and additionally incoming blood vessels that open into the retina to vascularize the retinal layers and neurons Fig. How the Eye Works.

Light entering the Eye 2. The retina is a light-sensitive layer that lines the back of the eye. Anatomy of Retina By DrAshok Kumar Valuroutu 2.

The purpose of the retina is to receive light that the lens has focused. Cone cells are the second type of light sensitive cells in the retina of the eye. Function of the retina-Transmit electrical impulse to the brain via ganglion cells - To absorb photons of light.

The retina consists of millions of cells packed together in a tightly knit network spread over the surface of the back of the eye. Sclera The white outer coat of the eye surrounding the iris. It is the area of the retina that is responsible for providing sharp central vision.

The neuroretina lays on the retinal pigmentary epithelium that together form the retina. The retina consists of 10 layers which include nine layers within the sensory retina and retinal pigment epithelium.

The following is a fundus photograph from a normal eye showing the macula green circle and fovea black circle. Lens also called crystalline lens. Anterior Chamber - The anterior chamber is the fluid-filled chamber between the iris and the corneas inner surface which is comprised of the endothelium.

Rete is the innermost light-sensitive layer of tissue of the eye of most vertebrates and some molluscs. The optics of the eye create a focused two-dimensional image of the visual world on the retina which translates that image into electrical neural impulses to the brain to create visual perception. The superior branch and the inferior branch.

Thin delicate layer of nervous tissue Surface area of 266 mm2 Extends from optic disc to ora serrata. Pupil - The pupil is the hole in the middle of the iris in which light pass through to the retina. The choroid is a layer of tissue that lies between the retina and the sclera.

Vitreous Humor The clear gelatinous substance filling the central cavity of the eye. The Anatomy and Physiology of Direction-Selective Retinal Ganglion Cells by Jinyue Liu Myriad Roles for Gap Junctions in Retinal Circuits Part IV. Embryologically RPE is developed from the outer layer of the optic cup and photoreceptors are developed from the inner layer of the cup and there is a potential space between RPE and sensory retina known subretinal space.

It is only 02 mm thick and is about the size of a silver dollar. ANATOMY Rate in Latin means Net proper thin delicate layer of the nervous tissue layer surface area of about 1094 mm2 Retina is a circular disc of between 30 40 mm in diameter The major landmark of the retina are - The optic disc The retina layer The macula Ora serrata 4. Neurotransmitters in the Retina.

Upon entering the nerve fiber layer of the retina the central retinal artery divides into two branches. The retina from Latin. Simple Anatomy of the Retina The retina is approximately 05 mm thick and lines the back of the eye.

It is located near the optic nerve. This fundus photograph shows the normal appearance of the retina. Macula and Optic Disc.

The retina senses light and creates electrical impulses that are sent through the optic nerve to the brain. Cellular anatomy of the retina. Each of the arterioles supplies one quadrant of the eye.

Photoreceptors absorb light and then convert and transmit those signals through the optic nerve to the brain.
