Ganglion Cells

Specialized neurons located in the retina that play a critical role in the visual system by transmitting image information from the photoreceptors to the brain.

Photoreceptor Cells

Specialized cells in the retina of the eye that respond to light, enabling vision by converting light into electrical signals.

Pupil
