Biology

The photoreceptor cells form the retina, a lamina that covers the internal posterior region of the eyeball. The photosensitive cells of the retina are divided into two types: the cone cells and the rod cells. These cells have pigments that sense specific light wave ranges (frequencies) and trigger action potentials conducted by the optical nerves to the visual area of the brain.
