célula fotorreceptora

célula fotorreceptora

A cell, functionally part of the nervous system, that reacts to the presence of light. It usually contains a pigment that undergoes a chemical change when light is absorbed. This chemical change stimulates electrical changes in the photoreceptor that, when passed along and processed by other neurons, form the basis of vision.
