Rods and cones of monkey retina. Light micrograph of a tangential section through the retina of a monkey's eye, showing the rod cells (small) and cone cells (large). Rod cells and the less numerous cone cells are specialized light- sensitive cells. They occur within the thickness of the retina, rather than on its surface. They are responsible for detecting visible images, which are transmitted as nerve impulses to the optic nerve and the brain. Rod cells detect light intensity and so are important for day and night vision. The less numerous cone cells respond specifically to colour. Magnification x2000 at 35mm size.
