Illustration of rod (orange) and cone (blue) photoreceptor cells in the retina of the eye. The retina is the light-sensitive tissue that lines the inside of the eye. Rods are long nerve cells that respond to dim light, enabling images to be detected. Cones are shorter cells that detect colour. Rods and cones pass visual signals through the optic nerve to the brain. | |
