conjunctiva (clear lining on the external and internal part) eyebrows, eyelashes, and eyelids lacrimal glands
34
what part of the eye is covered by conjunctiva?
sclera
35
what produce tears?
lacrimal glands
36
what part of the eye helps with focusing?
lens
37
what is the opening of the eye?
pupil
38
what surrounds the pupil and contracts to pupil size?
iris
39
what transmits and reflects light?
cornea
40
what is a non-allergic condition that causes a runny nose after eating certain foods, especially hot or spicy foods? what nerve does it impact?
gustatory rhinitis trigeminal nerve
41
What helps focus the lens of the eye?
ciliary body
42
the anterior chamber goes from _______________ to ______________.
iris to cornea
43
the posterior chamber goes from __________________ to ____________________
lens to iris
44
The ______________________ cavity involves the anterior and posterior chamber
anterior cavity
45
what is another word for the posterior cavity?
vitreous chamber
46
what eye structure divides the eye into two cavities?
lens
47
anterior cavity is _______________ humor
aqueous
48
the anterior cavity is from the ____________ to ____________________.
cornea to lens
49
what has a function of giving us binocular vision?
optic chiasm
50
for distant vision the ciliary muscles are _______________, lens is _________________, and suspensory ligaments are ________________.
ciliary= relaxed lens=flattened suspensory= taut
51
for near vision the ciliary muscles are _______________, lens is _________________, and suspensory ligaments are ________________.
ciliary= contracted (moving the ciliary body toward the lens) lens= thickened and more spherical suspensory= relaxed
52
what separates outer and middle ear?
ear drum (tympanic membrane)
53
where are the auditory ossicles and what are they called from outer to inner. what does the most inner one compress?
in the middle ear malleus -> incus -> stapes stapes compresses the oval window
54
the middle ear is also known as the _______________-
auditory tube
55
what cavity houses the auditory ossicles?
tympanic cavity
56
the ___________ is a hammer, the __________ is an anvil, and the _______________ is the stirrup
malleus incus stapes
57
round vs oval window
the oval window is the opening where the stapes bone transmits sound vibrations into the inner ear, while the round window acts as a pressure release valve, allowing fluid in the cochlea to move as sound waves enter through the oval window
