Detailed explanation-1: -The light image is mapped on the surface of the retina by activating a series of light-sensitive cells known as rods and cones or photoreceptors. The rods and cones convert the light into electrical impulses which are transmitted to the brain via nerve fibers.
Detailed explanation-2: -The light rays pass through the lens and focus on retina. It contains the photoreceptor cells. These cells convert the light signals into electrical impulses.
Detailed explanation-3: -The retina is the light-sensitive tissue at the back of the eye. The retina instantly converts light, or an image, into electrical impulses. The retina then sends these impulses, or nerve signals, to the brain.
Detailed explanation-4: -Nerve Impulse is defined as a wave of electrical chemical changes across the neuron that helps in the generation of the action potential in response to the stimulus. This transmission of a nerve impulse across the neuron membrane as a result of a change in membrane potential is known as Nerve impulse conduction.
Detailed explanation-5: -The light is mapped as an image along the surface of the retina by activating a series of light-sensitive cells which are known as rod cells and cone cells. These photoreceptor cells convert the light into electrical impulses, which are transmitted to the brain via nerve fibres.
