100
describe vasculature of the fibrous tunic
sclera is vascular and cornea is avascular
101
another name for suspensory ligaments
zonular fibers
102
where is the highest density of cones?
fovea centralis
103
what humor is replaced?
aqueous humor; vitreous is for life
104
pathway of aqueous humor
ciliary process, posterior chamber of anterior cavity, pupil, anterior chamber of anterior cavity, canal of schlemm, general blood circulation
105
what produces aqueous humor
ciliary process
106
pathway of tears
lacrimal glands, excretory duct, tears medially move across eye, lacrimal puncta, lacrimal canilliculi, lacrimal sac, nasolacrimal canal, inferior nasal meatus, nasal cavity
107
neural and pigmented layers of this structure separate. photoreceptors have no blood supply and die
detached retina
108
clouding of the lens due to inadequate delivery of nutrients
cataracts
109
why is their minimal rejection of corneal transplants
the cornea is an avascular layer
110
loss of near vision as the lens thickens and accommodation is lost with age
presbyopia
111
where does the lens focus in myopia
in front of the retina
112
describe eyeball in myopia
long
113
what lenses for myopia
concave
114
where does lens focus in hyperopia
behind retina
115
describe eyeball for hyperopia
short
116
what lenses for hyperopia
convex
117
more aqueous humor forms than is drained and pressure compresses the optic nerve
glaucoma
118
macula lutea deteriorates, building up pigment. there is a dry and wet form
age-related macular disease
119
infection of cornea or conjunctiva leading to inflammation which eventually causes scarring and blindness
trachoma
120
weak extrinsic eye muscles leading to being cross-eyed
strabismus
121
describe what is happening in far vision
ciliary muscles is relaxed making zonular fibers tense and a thin lens
122
describe what is happening in near vision
ciliary muscle contracts, relaxing zonular fibers, and creating a thick lens
123
pathway of sound
auricle/pinna, external auditory canal, tympanic membrane, malleus, incus, stapes, displaces perilymph in scala vestibuli, vibrates vestibular membrane, displaces endolymph in scala media, vibrates basilar membrane, hair cells rub against tectorial membrane, nerve impulse sent through cochlear branch of cn viii vestibulocochlear
124
innervation of tensor tympani
mandibular branch of cn v
125
innervation of stapedius
vii
126
used for sensorineural deafness. sound energy is converted into electric signals that directly stimulate the cochlear nerve
cochlear implants
127
sound conduction is impeded in the external or middle ear
conductive deafness
128
problem with the cochlea or neural pathway of hearing
senoriineural deafness
129
infection from throat goes to middle ear to mastoid air cells to the brain
mastoiditis
130
membranous labyrinth is distorted by excess endolymph that distorts equilibrium
meniere's disease
131
involuntary motion of the eye
nystagmus
132
another name for middle ear infection
otitis media
133
tiny tubes are inserted through the tympanic membrane to drain into the external ear for middle ear infectin
myringotomy
134
excessive growth of bone tissue makes it such that the stapes can't move resulting in deafness
otosclerosis
135
tear of tympanic membrane from otitis media or pressure from a cotton swab
perforated eardrum
136
gradual loss of hearing with age starting with high-pitched sounds
presbycusis
137
persistent noise often started to a head/cochlea injury or exposure to a loud noise
tinnitus
138
where do lower frequencies vibrate basilar membrane
closer to apex of cochlea
139
where do higher frequencies vibrate basilar membrane
closer to base of chochlea
140
frequencies change where basilar membrane vibrates
tonotopic organization
141
role of utricle
static equilibrium/ horizontal linear acceleration
142
role of saccule
static equilibrium; vertical linear acceleration
143
function of semicircular canals
monitor rotational acceleration of the head
