3 layers of the eyeball
sclera, choroid, retina
sclera
outer layer, provides a tough protective coating for the inner structures of the eye
cornea
the anterior portion of the sclera. If allows light to enter the eyeball
choroid
middle layer; provides the blood supply for the eye
anterior portion of the choroid layer
iris, pupil, ciliary body
iris
colored portion of the eye & contains smooth muscle
pupil
the opening in the center of the iris that allows light rays to enter the eyeball.
ciliary body
immediately posterior to the iris; a ring of smooth muscle.
lens
sits in the center of the ring of the ciliary body
retina
innermost layer; contains the sensory receptor cells that respond to light rays
rods and cones
rods are active in dim light and help us to see in gray tones.
cones are active only in bright light and are responsible for color vision.
muscles of the eye
four rectus and two oblique muscles
conjunctiva
a mucous membrane lining. A continuous covering on the underside of each eyelid and across the anterior surface of each eyeball. Seals the eyeball in the socket
lacrimal gland
located under the outer upper corner of each eyelid. Produce tears.
xer/o
dry
conjunctival
pertaining to the conjunctiva
extraocular
pertaining to being outside the eyeball
intraocular
pertaining to within the eye
iridal
pertaining to the iris
uveal
pertaining to the choroid layer of the eye
blepharoptosis
drooping eyelid
diplopia
condition of seeing double
emmetropia
state of normal vision
iridoplegia
paralysis of the iris
cyclophegia
paralysis of the ciliary body
nyctalopia
difficulty seeing in dim light; night blindness
scleromalacia
softening of the sclera

study of the ear
otology
study of hearing disorders
audiology
2 senses the ear is responsible for
hearing and equilibrium
three areas of the ear
external ear, middle ear, and inner ear
3 parts of the external ear
auricle, auditory canal and the tympanic membrane
the visible portion of the ear
auricle or pinna
earwax or cerumen
produced in oil glands in the auditory canal. Wax helps to protect and lubricate the ear. Helps the auditory canal to be self-cleaning.
Bones in the middle ear
malleus, incus, and stapes
eustachian tube jor auditory tube
air filled cavity connects the nasopharynx with the middle ear. Each time you swallow the eustachian tube opens. This connection allows pressure to equalize between the middle ear cavity and the atmospheric pressure.
inner ear
fluid filled cavity referred to as the labryinth.
acoustic
pertaining to hearing
aural
pertaining to the ear
binaural
pertaining to both ears
monaural
pertaining to one ear
macrotia
condition of having abnormally large ears
microtia
condition of having abnormally small ears
otalgia
ear pain
tinnitus
ringing in the ears
tympanorrhexis
rupture of the tympanic membrane
anacusis
total absence of hearing
ceruminoma
excessive accumulation of earwax resulting in a hard wax plug
otitis externa
external ear infection…swimmer’s ear
myringitis
inflammation of the tympanic membrane
otosclerosis
loss of mobility of the stapes bones, leading to progressive hearing loss
otitis media
middle ear infection
salpingitis
inflammation of the auditory tube
otoplasty
surgical repair of the external ear
stapedectomy
surgical removal of the stapes bone to treat otosclerosis.
