Rods and cones of the retina. False-colour scanning electron micrograph (SEM) of rod and cone cells of the eye retina. Rod cells (orange) and less numerous cone cells (blue) are specialized light-sensitive cells. They occur on the surface of the retina. They are responsible for detecting visible images,which are transmitted as nerve impulses to the optic nerve and the brain. There are about 130 million rod cells in the human retina; they detect light intensity and so are important for day and night vision. While the less numerous cone-like cone cells (about 6.5 million in the human retina) respond specifically to colour. Magnification: unknown | |
