Retina Function, Anatomy Anatomy Body Maps Retina It is located near the optic nerve The purpose of the retina is to receive light that the lens has focused, convert the light into neural signals, and send these signals on to the brain for visual recognition The retina processes light through a layer of photoreceptor cells. retina Definition, Function, Facts Britannica Retina Light sensitive molecules in the rods and cones react to specific wavelengths of light and trigger nerve impulses Complex interconnections synapses between and within retinal cell layers assemble these impulses into a coherent pattern, which in turn is carried through the optic nerve to the visual centres of the brain, Retina The Retina of the Human Eye Georgia State University The Retina The retina is a light sensitive layer at the back of the eye that covers about percent of its interior surface Photosensitive cells called rods and cones in the retina convert incident light energy into signals that are carried to the brain by the optic nerve. The Retina Neuroscience NCBI Bookshelf Despite its peripheral location, the retina or neural portion of the eye, is actually part of the central nervous system During development, the retina forms as an outpocketing of the diencephalon, called the optic vesicle, which undergoes invagination to form the optic cup Figure . see also Chapter The inner wall of the optic cup gives rise to the retina, while the outer wall gives Retina Definition and Detailed Illustration Retina Definition The retina is the sensory membrane that lines the inner surface of the back of the eyeball It s composed of several layers, including one that contains specialized cells called photoreceptors Light rays are focused by the cornea and lens onto the retina, where vision begins.
