Eye and Ear Diagrams
- Eye
- Aqueous humour
- Watery fluid that is produced by the ciliary body and lies in between the lens and cornea in order to lubricate them.

- Cornea
- Clear membrane that lies in front of the iris and bends light into the lens.
- Clear membrane that lies in front of the iris and bends light into the lens.
- Lens
- A flexible structure that allows light to be focused on the retina.

- Ciliary body
- Conjuctiva
- A membrane that covers the sclera.
- A membrane that covers the sclera.
- Choroid
- Nourishes and supplies the retina with blood

- Sclera
- White part of the eye.
- White part of the eye.
- Cone Cells and Rod Cells
- Cone cells come in 3 different ways (red, blue and green) and help you see in colour and brightly lit areas while rod cells help you see in dimly lit areas. Both are found in the retina, cone cells are mostly concentrated in the fovea centralis.

- Eye muscles
- Vitreous humour
- Dilator muscle
- Sphincter muscle
- Iris
- Pupil
- Aqueous humour
- Ear
- Pinna
- The outer ear, which funnels sound into the ear canal.
- The outer ear, which funnels sound into the ear canal.
- Eardrum
- A thin flap of skin that separates the outer and middle ear and vibrates when sound reaches it.
- A thin flap of skin that separates the outer and middle ear and vibrates when sound reaches it.
- Ossicles
- When vibrations pass onto the hammer, anvil and stirrup (the ossicles), the Ed become amplified.

- Oval window
- Oval window
- A thin layer of tissue that separates the middle and inner ear and transmits vibrations from the stirrup to the cochlea.

- Semicircular canals
- Fluid-filled tubes that give us our sense of balance and may be affected by ear infections and problems.
- Fluid-filled tubes that give us our sense of balance and may be affected by ear infections and problems.
- Auditory nerve
- Sends electrical impulses to the brain which we then interpret as sound.
- Is in the iris and enlarges the pupil, allowing more light in the eye in dimly lit areas.

- Sends electrical impulses to the brain which we then interpret as sound.
- Cochlea
- Is in the iris and shrinks the pupil, allowing less light in the eye in brightly lit areas.
- Fluid-filled and spiral-shaped tube that has tiny hairs on in that detect the movement if fluid caused by vibrations. The tiny hairs convert the vibrations into electrical impulses.
- Is in the iris and shrinks the pupil, allowing less light in the eye in brightly lit areas.
- Eustachian tube
- Tube that connects middle ear, nose and throat and controls air pressure on the other side of the eardrum.
