GROSS ANATOMY

Detailed explanation-1: -The retina is covered with millions of light sensitive cells called rods and cones. When these cells detect light, they send signals to the brain. Cone cells help detect colors.

Detailed explanation-2: -Cones contain photo pigments, or color-detecting molecules. Humans typically have three types of photo pigments-red, green and blue. Each type of cone is sensitive to different wavelengths of visible light. In the daytime, a lemon’s reflected light activates both red and green cones.

Detailed explanation-3: -There are 2 types of photoreceptors: rods, which detect dim light and are used for night vision, and cones, which detect different colors and require brightly lit environments.

Detailed explanation-4: -Cones are a type of photoreceptor cell in the retina. They give us our color vision. Cones are concentrated in the center of our retina in an area called the macula and help us see fine details. The retina has approximately 120 million rods and 6 million cones.

Detailed explanation-5: -The rods are sensitive to light intensity or brightness, and they don’t respond to color. It is the rods that allow us to see in low light situations.
