Verified step by step guidance

Understand the structure of the retina, which is the light-sensitive layer at the back of the eye. It contains photoreceptor cells known as rods and cones, which are responsible for detecting light.

Recognize that once light is absorbed by the photoreceptors (rods and cones), it triggers a chemical change that generates a nervous signal.

Identify the pathway of the nervous signal: The signal first travels from the photoreceptors (rods and cones) to the bipolar cells. Bipolar cells act as intermediaries, transmitting signals from the photoreceptors to the ganglion cells.

Understand that ganglion cells are the final output neurons of the retina. They receive signals from the bipolar cells and their axons form the optic nerve, which carries visual information to the brain.

Consider the role of other retinal cells such as horizontal and amacrine cells, which modulate the signal between photoreceptors and ganglion cells, but are not part of the direct pathway from photoreceptors to ganglion cells.
