MICROANATOMY

Detailed explanation-1: -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. Humans have 3 distinct color-sensing cones-for red, green, and blue light.

Detailed explanation-2: -Rods and cones are two types of photoreceptors in the eye. Both are specialized nerves that convert light into neural impulses, but they differ in number, location, and function. Rods are more numerous, located in the periphery of the eye, and good for detecting light in general.

Detailed explanation-3: -Photoreceptor types. There are four photoreceptor types in the human retina. Short-wavelength cones (blue), medium-wavelength cones (green), long-wavelength cones (red) and rods..

Detailed explanation-4: -Scientists have known for decades that some cells-known as cones-detect color. They are part of the retina inside the back of the eye. Cone cells can sense red, green or blue light.
