Anatomy Of The Eye Retina

Arteriovenous Crossings This is a frame from the midphase of a fluorescein angiogram of the inferotemporal quadrant of the retina of a normal eye. In the diagram above - anatomy of the eye the artery is shown in red while the vein is shown in blue.

The optical elements within the eye focus an image onto the.

Anatomy of the eye retina. There are two types of photoreceptor cells in the human eye rods and cones. Anatomy of the Eye. Structure containing muscle and is located behind the iris which focuses the lens.

The retina is a thin layer of tissue that lines the back of the eye on the inside. The retina is made up of 200 million neurons many of which are photoreceptors. It consists of a central area called the macula and a larger peripheral area of the retina.

Eyes diagram showing the entire structure The sclera. Our retina is about the size of a postage stamp. Cornea - The cornea is the clear dome-like structure on the front part of the eyeThe cornea delivers 23 of the refracting power to the eye.

Rete is the innermost light-sensitive layer of tissue of the eye of most vertebrates and some molluscsThe 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 perceptionThe retina serves a function analogous to that of the film or image. The retina is a specialized layer of neural tissue that coats the back of the eye. The part of the eye that connects the choroid to the iris.

The orbit also contains the lacrimal gland that is located underneath the outer portion of the upper eyelid. Broadly retina consists of two primary layers. The central artery and vein runs through the center of the optic nerve.

The retina functions in a manner similar to film in a camera. It contains several layers including a layer that contains photoreceptors. Its composed of several layers including one that contains specialized cells called photoreceptors.

It is made of a dense strong fibrous wall consisting of the sclera that is 56 th and the cornea that is anterior 16 th of the eyeball. Photoreceptors absorb light and then convert and transmit those signals through the optic nerve to the brain. Conjunctiva - The conjunctiva is a mucus membrane that covers the surface of the eye and the inner part of the eyelids.

Although the retina can easily be compared to the film inside a camera that analogy is misleading because the retina is very complex. The sclera is the outermost layer and it gives a definite shape to the eye. In addition to the eyeball itself the orbit contains the muscles that move the eye blood vessels and nerves.

The transparent structure inside the eye that focuses light rays onto the retina. Anatomy of the Eye. Lens also called crystalline lens.

The retina of human eye is the sensory membrane that lines the inner surface of the back of the eyeball. 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. An inner neurosensory retina and retinal pigment epithelium RPE.

The iris is partly responsible for regulating the amount of light permitted to enter the eye. It is an outgrowth of the brain and therefore can be classified as a member of the central nervous system. The purpose of the retina is to receive light that the lens has focused.

The retina is approximately 05 mm thick and lines the back of the eye. The human eye contains about 125 million rods which are necessary for seeing in dim light. The central artery supplies the retina while the central vein drains the retina.

It is located near the optic nerve. A light sensitive layer that lines the interior of the eye. Cones on the other hand function best in bright light.

The retina from Latin. It is composed of light sensitive cells known as rods and cones. The eye is cushioned within the orbit by pads of fat.

The retina is the light-sensitive tissue that lines the inside of the eye. It is only 02 mm thick and is about the size of a silver dollar. The retina is the innermost of the three coats of the eye.

The retina is a light-sensitive layer that lines the back of the eye. The yellow arrows indicate arteriovenous crossings in which the artery lies in front of the vein. The turquoise arrow indicates an arteriovenous crossing in which the vein lies in front of the artery.

The retina is the sensory membrane that lines the inner surface of the back of the eyeball. This layer is responsible for converting relevant information from the image of the external environment into neural impulses that are transmitted to the brain.

Sclera - The sclera is the white tough outer covering of globe of the eye. It makes up the outermost part of eye anatomy. Layer containing blood vessels that lines the back of the eye and is located between the retina the inner light-sensitive layer and the sclera the outer white eye wall.
