This structure controls how much light enters the eye.
What is the iris?
The outer ear structure that collects sound.
What is the pinna?
A student walks from a dark hallway into bright sunlight and squints. This part of the eye is adjusting.
What is the pupil
This condition causes blurred vision due to an irregularly shaped cornea or lens.
What is astigmatism?
This sense helps you detect chemicals in the air and is closely linked to memory.
What is smell?
This structure is where the optic nerve exits the eye, creating a blind spot.
What is the optic disc?
These tiny bones amplify sound vibrations.
What are ossicles?
You spin in circles and suddenly feel dizzy. This part of your ear is responsible
What are the semicircular canals?
This disorder results in difficulty seeing far-away objects clearly.
What is myopia?
These receptors in the skin respond specifically to temperature changes.
These receptors in the skin respond specifically to temperature changes.
This membrane covers the white part of the eye and helps protect it.
What is the conjunctiva?
This part of the ear is responsible for balance.
What are semicircular canals?

What is presbyopia?
This structure in the inner ear helps detect head movement and position.
What are semicircular canals?
This is where images are formed in the eye.
What is the retina?
Sound vibrations are converted into nerve signals here.
What is the cochlea?
A person touches a hot stove and pulls away quickly. These receptors detected the heat and pain.
What are skin receptors (touch/pain receptors)?
This type of hearing loss occurs due to damage to the inner ear or auditory nerve.

This part of the tongue detects different taste qualities like sweet, salty, sour, and bitter.
What are taste buds?
This fluid maintains the shape of the eye and fills the back portion.
What is vitreous humor?
This structure equalizes pressure in the ear
What is the Eustachian tube?
A musician stands too close to loud speakers for years and develops hearing issues. This structure is likely damaged.
What are hair cells in the cochlea?
This serious eye condition occurs when the retina pulls away from its normal position.
What is retinal detachment?
This cranial nerve is responsible for transmitting smell information to the brain.
What is the olfactory nerve?
