The Eye
Name the three layers of the eye.
Sclera, Choroid Coat (Choroid), Retina
Which structure separates the outer ear from the middle ear and vibrates to send soundwaves into the middle ear?
Tympanic Membrane
Which condition occurs when the normally clear lens becomes cloudy or opaque due to aging or trauma?
Cataract
Which eye condition has signs/symptoms such as redness, swelling, pain, pus formation, and matting of the eyelashes?
Conjunctivitis
True or False: 75% - 90% of what we taste is due to smell.
True
Which type of neurons are used to detect vision in bright light?
Cones
Location: Middle Ear
Function:It allows air to enter the middle ear & helps equalize pressure within the ear.
What type of hearing loss occurs when sound waves are unable to make their way to the inner ear?
Conductive Hearing Loss
Which condition is an inflammation of the auditory canal, usually caused by a bacteria or virus? It is also known as "Swimmer's Ear."
Otitis Externa
Name the three ossicles found in the middle ear?
malleus, incus, stapes
What is the jellylike substance, which fills the area behind the lens, helps maintain the shape of the eyeball, and refracts light rays?
Vitreous Humor
In which specific part of the ear is cerumen produced?
The auditory canal
(cerumen = ear wax)
Which condition occurs due to increased intraocular pressure, which is caused by excess aqueous humor building up within the eye and may lead to blindness?
Glaucoma
Which eye condition is caused by age related changes and is treated by using reading glasses?
Presbyopia
In which part of the tongue are taste buds for sweet and salty tastes more concentrated?
The tip of the tongue
What is the transparent, circular area on the front of the sclera that allows light rays to enter the eye?
Cornea
Which specific part of the ear sends impulses to the cerebellum, which allows us to maintain balance and equilibrium?
Semi-circular canals
Which condition occurs when the stapes becomes immobile due to abnormal bone growth in the middle ear and causes a conductive hearing loss?
Otosclerosis
Which eye condition occurs when the central and most sensitive section of the retina is damaged and leads to loss of central vision?
Macular Degeneration
What is the term for age related hearing loss?
Presbycusis
What is the circular structure located behind the pupil, that refracts light rays and changes shape to acoommodate for near and far vision?
Lens
What are the hairlike cells located in the cochlea, which are the receptors for sound waves?
Organ of Corti
What condition occurs when the eyes do not move or focus together due to muscle weakness in one or both eyes? Sometimes it is called, "cross eyed."
Strabismus
Which condition results from a build up of fluid in the inner ear, which causes degeneration of the hair cells in the cochlea & vestibule and leads to vertigo, tinnitus, loss of balance and falls?
Meniere's Disease
Which condition occurs when there is an abnormal shape or curvature of the cornea, which causes light to hit multiple areas on the retina and results in blurred vision?
Astigmatism
