Final answer:
The receptors in the visual pathway are cones and rods, where cones are responsible for color vision and rods for low-light and peripheral vision.
Step-by-step explanation:
The receptors of the visual pathway are a. cones and rods. These photoreceptors are located in the retina of the eye, with cones being primarily responsible for color vision and rods for vision in low light. Cones are found in high density in the fovea, the central region of the retina, and provide sharp central vision. On the other hand, rods are more dispersed throughout the retina, predominantly around the periphery, and are sensitive to motion and dim light.
what the receptors of the visual pathway are is a. cones and rods. It is important to note that statement (a), suggesting rods detect color, is false; rods actually detect only shades of gray. Statement (c) is true as the iris does indeed adjust the amount of light that enters the eye, while (d) incorrectly describes the fovea as a protective layer—it is actually a key area for sharp vision.
Cones are responsible for color vision and are found in the central region of the retina called the fovea. Rods, on the other hand, are responsible for vision in low light conditions and are located in the peripheral regions of the retina. Together, cones and rods play a crucial role in our visual perception.
