Hint
Answer
Attached to suspensory ligaments and control the position of the lens so it can focus the light by contracting/relaxing.
Ciliary Muscle
Sit either side of the lens and hold it in position.
Suspensory Ligaments
Made up of muscles which contract/relax to control the size of the pupil, as well as how much light enters the eye.
Iris
A hole located in the centre of the iris allowing light to strike the retina.
Pupil
A clear disc controlled by the ciliary muscles and suspensory ligaments that focuses light rays to produce a clear image of the retina.
Lens
Hint
Answer
A transparent area of the sclera at the front of the eyeball, letting light in and playing an important role in focussing light rays onto the retina.
Cornea
An area at the back of the eye containing clusters of light-sensitive cells.
Retina
The white, outer layer of the eye; tough and strong so little damage can be done to the eyeball.
Sclera
The point where the optic nerve leaves the eye; no retina is located here, therefore there are no light-sensitive cells.
Blind Spot
Sends impulses to the brain collected by sensory neurones when light-sensitive cells in the retina are stimulated.
Optic Nerve
