Quizplus · Accepted Answer

Ganglion cells are the final stage of retinal processing before the visual signal is sent to the brain. They generate action potentials that travel along their axons, which converge to form the optic nerve. Rods and cones are photoreceptor cells that detect light and initiate a chain of chemical events that ultimately lead to the generation of an electrical signal in bipolar cells. However, rods and cones themselves do not generate action potentials. Bipolar cells are intermediate neurons in the visual pathway that transmit information from photoreceptor cells to ganglion cells. Epithelial cells are not directly involved in visual processing.
