Retina. Coloured scanning electron micrograph (SEM) of the structure of the eye retina. The light-sensitive retina detects visible images. It consists of many layers of cells, seen here. Light strikes from below. At top is the surface of pigment cells (white). Directly beneath lie close- packed rod and cone cells (pink). More numerous rod cells appear as lighter fibres; cone cells are darker and cone-like. While rod cells detect light intensity, cone cells respond to colour. A deeper layer of round nerve cells transmits impulses from rods and cones to optic nerve fibres (grey, at bottom centre). Magnification: x400 at 6x7cm size. Magnification: x650 at 4x5 inch size.
