Which visual receptor is more numerous in the retina?

Rods are the visual receptors that are more numerous in the retina, significantly outnumbering cones. In fact, in the human retina, there are approximately 120 million rods compared to about 6 million cones. Rods are highly sensitive to light, enabling them to function well in low-light conditions, which is why they are crucial for night vision. They do not perceive color but are responsible for detecting motion and shapes in dim environments.

Cones, on the other hand, are less numerous and are concentrated in the central part of the retina (the fovea), where they excel in daylight conditions and are responsible for high-resolution color vision. Photoreceptors is a broader term that includes both rods and cones, while nerve endings refer to a different type of cell component altogether. Therefore, rods are the correct answer as they comprise the majority of the photoreceptors in the retina.
