Receptor that is sensitive to light
A photoreceptor cell is a specialized type of neuroepithelial cell found in the retina that is capable of visual phototransduction. The great biological importance of photoreceptors is that they convert light (visible electromagnetic radiation) into signals that can stimulate biological processes. To be more … Visa mer Each photoreceptor absorbs light according to its spectral sensitivity (absorptance), which is determined by the photoreceptor proteins expressed in that cell. Humans have three classes of cones (L, M, S) that each … Visa mer Most vertebrate photoreceptors are located in the retina. The distribution of rods and cones (and classes thereof) in the retina is called the retinal mosaic. Each human Visa mer The key events mediating rod versus S cone versus M cone differentiation are induced by several transcription factors, including RORbeta, … Visa mer Rod and cone photoreceptors are common to almost all vertebrates. The pineal and parapineal glands are photoreceptive in … Visa mer Rod and cone photoreceptors are found on the outermost layer of the retina; they both have the same basic structure. Closest to the visual field (and farthest from the brain) is the Visa mer The path of a visual signal is described by the phototransduction cascade, the mechanism by which the energy of a photon signals a … Visa mer Intrinsically photosensitive retinal ganglion cells (ipRGCs) are a subset (≈1–3%) of retinal ganglion cells, unlike other retinal ganglion cells, are intrinsically photosensitive due … Visa mer WebbLight passes through the eyeball to the retina. There are two main types of light receptors - rods and cones. Rods are more sensitive to light than cones so they are useful for …
