GENERAL HISTOLOGY

Detailed explanation-1: -The retina is a layer of photoreceptors cells and glial cells within the eye that captures incoming photons and transmits them along neuronal pathways as both electrical and chemical signals for the brain to perceive a visual picture.

Detailed explanation-2: -The retina (pronounced: RET-nuh), the innermost of the three layers, lines the inside of the eyeball. The retina is a soft, light-sensitive layer of nervous system tissue. The optic nerve carries signals from the retina to the brain, which interprets them as visual images.

Detailed explanation-3: -Photoreceptors are specialized neurons found in the retina that convert light into electrical signals that stimulate physiological processes. Signals from the photoreceptors are sent through the optic nerve to the brain for processing.

Detailed explanation-4: -The retina contains many types of cells. Photoreceptors process light into an electrical signal that your brain can understand as images. Rods are photoreceptors that help you see at night and in dim light. Cones process color and make up most of your usual vision.

Detailed explanation-5: -The retina consists of millions of cells packed together in a tightly knit network spread over the surface of the back of the eye. These cells can be divided into a three basic cell types, photoreceptor cells, neuronal cells, and glial cells. Photoreceptor cells consist principally of cones and rods.
