membrane situated inside the back of the eye that is sensitive to light stimuli
Note 1 to entry: The retina contains photoreceptors and nerve cells that interconnect and transmit to the optic nerve the signals resulting from stimulation of the photoreceptors. The photoreceptors in the human retina are of three types: rods and cones, which are responsible for vision, and intrinsically photosensitive retinal ganglion cells (ipRGCs), which play a role in controlling circadian and neuro-endocrine systems.
