Potpourri
100
This is the scientific name for the white part of the eyeball.
What is the sclera?
100
These are the color sensing cells of the retina.
What are cones?
100

Translates sound vibrations into nerve impulses; controls both static and dynamic equilibrium

What is vestibular system?

100
This is the name of the most external and visible portion of the ear.
What is the pinna (auricle)?
100

Globe-shaped organ that consists of three layers.

What is eyeball?

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

Dilates to allow more light to enter the eye; constricts to decrease the amount of light entering the eye

What is pupil?

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

Dilates to allow more light to enter the eye; constricts to decrease the amount of light entering the eye

What is the pupil?

300

Dark blue middle layer that supplies blood to the entire eye

What is the choroid?

300
This is the name of the crossing of the optic nerve fibers in the brain.
What is the optic chiasm?
300

Vibrations of the tympanic membrane cause these three tiny bones to move, sending vibrations to the inner ear

What are the ossicles?

300

Snail-shaped structure of the inner ear lined with the Organ of Corti and filled with perilymph; part of the vestibular system

What is cochlea?

400
This structure is responsible for producing tears.
What is the lacrimal gland?
400

Pale, transparent fluid within the labyrinth that responds to changes in body position based on gravity

What is endolymph?

400

Attached to the retina; transmits visual information to the brain

What is the optic nerve?

400

Thin mucous membrane covering the outer surface of the eye that contains blood vessels and secretory glands

What is conjunctiva?

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

Surrounds the pupil and gives the eyes their color

What is the iris?

500

Attached to the lens; includes several ciliary muscles

What is the ciliary body?

500
This is the name of the reflex tested by briefly shining a light into the eye and watching for constriction and dilation.
What is the pupillary reflex?
