Which types of cells are present in the retina?

The retina contains specialized cells known as rods and cones, which are types of photoreceptor cells responsible for converting light into visual signals. Rods are sensitive to low light levels and are primarily responsible for night vision, while cones operate in brighter light and enable the perception of color and fine detail. Together, these cells allow the retina to adapt to different lighting conditions and provide a wide range of visual information to the brain.

Neurons and glia also play important roles in the retina, but the question specifically asks for types of cells present in the function of visual processing, making rods and cones the more accurate answer in this context. Fibroblasts and epithelial cells do not have a role in the primary function of image detection in the retina, and photomultiplier cells are not physiological components of retinal structure but rather devices used in various scientific applications to detect light. Understanding the specific types of functional cells in the retina is essential for grasping how vision is processed and the unique adaptations for light detection.
