100
These are the grey-scale sensing cells of the retina.
What are rods?
100
This is the name of the most external and visible portion of the ear.
What is the pinna (auricle)?
100
This is the shape or form that sound travels in.
What are waves?
200
These structures shade our eyes from the sun, and protect them from dirt and debris.
What are eylashes?
200
This conditions of the eyeball is a result of blocked aqueous humor flow, and results in increased internal pressure of the eye.
What is a glaucoma?
200
This is the name of the nerve emerging from the back of each eyeball.
What is optic nerve?
200
This structure is where sound is first sensed as sound waves.
What is the tympanic membrane (eardrum)?
200
This is the name of the hole (in the middle of the iris) that opens and closes depending on the light conditions.
What is the pupil?
300
This is the blood vessel rich, middle layer of the eye.
What is the choroid?
300
This muscle pulls on the lens to focus our vision at different distances.
What is the choroid body?
300
This is the name of the crossing of the optic nerve fibers in the brain.
What is the optic chiasm?
300
These are the names of the 3 smallest bones of the body (located in the middle ear).
What are the malleus (hammer), incus (anvil), and stapes (stirrup)?
300
This structure of the ear is a direct connection from the middle ear to the throat, and is the pathway responsible for many middle ear infections.

This is the name of the muscle that opens and closes the pupil depending on light conditions.
What is the iris?
400
This is the lobe of the brain that is involved in processing visual information from the eyes.
What is the occipital lobe?
400
This is the lobe of the brain which processes auditory information from the ears.
What is the temporal lobe?
400
This is an eye condition in which the normally clear and pliable lens becomes cloudy and stiff, producing blurry vision.
What is a cataract?
500
This is the name of the layer of clear sclera tissue covering the front of the eye.
What is the cornea?
500
This is the biconvex, crystal-like, clear structure which can change shape to focus light precisely onto the posterior, internal eye.
What is the lens?
500
Once the medial fibers from each optic nerve cross, they synapse (pitstop) in this structure before traveling the the cerebrum. This serves as a relay center for these nerve fibers.
What is the thalamus?
500
This is the name of the structure of the inner ear that is senses the bodys equilibrium and position in space.
What is the vestibule (vestibular apparatus)?
500
This is the name of the reflex tested by briefly shining a light into the eye and watching for constriction and dilation.
