PATHOLOGY

Detailed explanation-1: -Rod and cone photoreceptors are specialized neurons that function in the initial step of vision. These light-sensitive cells lie at the back of the retina adjacent to the retinal pigment epithelium (RPE), a cell layer that is vital for the survival of photoreceptors.

Detailed explanation-2: -As we have seen from the morphological appearances described above, two basic types of photoreceptor, rods and cones, exist in the vertebrate retina (Fig.

Detailed explanation-3: -There are two types of photoreceptors: rods and cones. Rods are more sensitive to light, making them primarily responsible for vision in low-lighting conditions like at night. Cones are less sensitive to light and are most active in daylight conditions. The cones are also responsible for color vision.
