Question 1

?When the curve of the cornea is uneven, vision becomes blurred; this condition is called:
A) ?astigmatism
B) ?hyperopia
C) ?myopia
D) ?presbyopia

Accepted Answer

Astigmatism is the condition where the curve of the cornea is uneven, leading to blurred vision because light rays are not focused sharply on the retina.

Question 2

?A serious age-related deterioration that results in blindness:
A) ?cataracts
B) ?glaucoma
C) ?macular degeneration
D) ?astigmatism

Accepted Answer

Macular degeneration is a serious age-related condition that affects the macula, leading to vision loss and potentially resulting in blindness.

Question 3

?The medical term for eardrum is:
A) ?external auditory meatus
B) ?pinna
C) ?tympanic membrane
D) ?cochlea

Accepted Answer

The tympanic membrane is the medical term for the eardrum, which is a thin membrane that separates the external ear from the middle ear and is involved in hearing.

Question 4

?The ossicles are composed of the:
A) ?eustachian tube and cochlea
B) ?malleus, stapes, and incus
C) ?vestibule and cochlea
D) ?pinna and cochlea

Accepted Answer

The ossicles are the three small bones in the middle ear known as the malleus, stapes, and incus. These bones play a crucial role in transmitting sound vibrations from the eardrum to the inner ear.

Question 5

?The inner ear may be called the:
A) ?auricle
B) ?labyrinth
C) ?ossicles
D) ?pinna

Accepted Answer

The inner ear is often referred to as the labyrinth due to its complex structure of interconnecting tunnels and chambers.

Question 6

?One purpose of fluid in the middle ear is to:
A) ?gather sounds
B) ?maintain balance
C) ?produce cerumen
D) ?vibrate cilia

Accepted Answer

The fluid in the middle ear plays a role in maintaining balance, as part of the vestibular system which is connected to the inner ear. The other options are not functions of the fluid in the middle ear.

Question 7

?Hypermetropia is due to a(n):
A) ?inward turning of the eyeball
B) ?refraction error
C) ?deterioration of the macula lutea
D) ?shortening of the retina

Accepted Answer

Hypermetropia, also known as farsightedness, is a common vision condition resulting from a refraction error where the eye does not bend or refract light properly to a single focus to see images clearly.

Question 8

?Inability of the aqueous humor to drain from the anterior cavity results in:
A) ?glaucoma
B) ?macular degeneration
C) ?retinal tears
D) ?cataracts

Accepted Answer

Glaucoma is caused by the inability of the aqueous humor to drain properly from the anterior chamber of the eye, leading to increased intraocular pressure which can damage the optic nerve.

Question 9

?A condition characterized by involuntary, rapid rhythmic movement of the eyeball is:
A) ?hyperkinesis
B) ?myoclonus
C) ?nystagmus
D) ?anisocoria

Accepted Answer

Nystagmus is the condition described, characterized by involuntary, rapid, rhythmic movement of the eyeball. Hyperkinesis refers to excessive movement but is not specific to the eyes, myoclonus involves sudden muscle spasms, and anisocoria refers to unequal pupil sizes.

Question 10

?A buildup of pus in the middle ear is ___________ otitis media:
A) ?hemorrhagic
B) ?purulent
C) ?serous
D) acute

Accepted Answer

Purulent otitis media is characterized by a buildup of pus in the middle ear, which is a sign of infection. The term "purulent" specifically refers to the presence of pus.

B)iris
C)refraction
D)myopia
E)sclera
F)macula lutea
G)cataract
H)pupil
I)uvea
J)vitreous humor

Accepted Answer

The macula lutea is the area in the retina where the cones, responsible for color vision and high acuity vision, are densely packed.

Question 13

-?Maintains the shape of the eyeball
A)aqueous humor
B)iris
C)refraction
D)myopia
E)sclera
F)macula lutea
G)cataract
H)pupil
I)uvea
J)vitreous humor

Accepted Answer

The vitreous humor is a clear gel that fills the space between the lens and the retina in the eyeball, helping to maintain its shape.

Question 14

A)aqueous humor
B)iris
C)refraction
D)myopia
E)sclera
F)macula lutea
G)cataract
H)pupil
I)uvea
J)vitreous humor

Accepted Answer

The uvea is the middle layer of the eyeball, consisting of the iris, ciliary body, and choroid.

Question 15

A)aqueous humor
B)iris
C)refraction
D)myopia
E)sclera
F)macula lutea
G)cataract
H)pupil
I)uvea
J)vitreous humor

Accepted Answer

Refraction is the bending of light as it passes from one medium to another, which is a fundamental principle in the physics of light and optics, including how the eye focuses light to form images on the retina.
