A specialized structure or cell that is sensitive to light. In vertebrate animals, the photoreceptors are the rods and cones of the eye's retina. See Note atcircadian rhythm. The American Heritage® Student Science Dictionary, Second Edition. Copyright © 2014 by Houghton Mifflin Harcourt Publi...

Visual sensations that persist after a stimulus is removed, like seeing a spot after a flashbulb goes off, are called: a. limens. b. phosphenes. c. afterimages. d. photoreceptors. Sensory localization means that the sensat...

What are cell surface receptors? Which portion of the eye is covered by conjunctiva? What body part has the least amount of touch receptors? What part of a neuron carries messages to other cells? What part of the retina lacks photoreceptors?
The anterior pole of the eye, composed of the cornea, iris, and lens, serves to focus light onto the photoreceptors of the retina. The retina is a layered structure composed of retinal ganglion cells, amacrine cells, horizontal cells, and photoreceptors that transduces, processes, and integrates...
Photoreceptors are the sensory receptors that respond to light energy which results in a graded change in membrane potential that is propagated... Learn more about this topic: Back of the Eye & Retinal Receptors | Rods, Cones & Anatomy
The receptors of the eye conduct information by catching light particles and converting the information into electrical signals that the brain can process into an image. Learn about photoreceptors, photopsin, rhodopsin, and the optic nerve.
The posterior pole of the eye contains the neural, or sensory, retina, comprising a combination of sensory neurons (e.g., photoreceptors), second and third order neurons (e.g. bipolar cells and ganglion cells) and the retinal pigment epithelium (RPE), which lies on a basement membrane (Bru...
