What is the function of iris?
region with the highest density of cones
hole that allows light to enter the eye
sensory neurone that carries impulses b
between the eye and the brain
controls how much light enters the pupil
What is the function of pupil?
region with the highest density of cones
hole that allows light to enter the eye
sensory neurone that carries impulses
between the eye and the brain
controls how much light enters the pupil
What is the function of fovea?
region with the highest density of cones
hole that allows light to enter the eye
sensory neurone that carries impulses
between the eye and the brain
controls how much light enters the pupil
What is the function of blind spot?
region with the highest density of cones
hole that allows light to enter the eye
sensory neurone that carries impulses
between the eye and the brain
point at which the optic nerve leaves the eye, where there are no receptor cells
What is the function of retina?
point at which the optic nerve leaves the eye, where there are no receptor cells
transparent disc that can change shape to focus light
tissue containing receptor cells where the image of an object fell on
controls how much light enters the pupil
What is the function of lens?
point at which the optic nerve leaves the eye, where there are no receptor cells
transparent disc that can change shape to focus light onto the retina
tissue containing receptor cells where the image of an object fell on
controls how much light enters the pupil
What is the function of conjuctiva?
clear membrane that covers the white of the eye and the inside of the
eyelids
lubricates the eye
provides protection from external irritants
controls how much light enters the pupil
transparent lens that refracts light as it enters the eye
