Eyes and Ears
25
sight: most dominant of the human senses
three: the number of layers the wall of the eyeball consists of
sclera: the "white of the eye"
shape: the function of the sclera
cornea: transparent structure that bulges out; contains no blood vessels
limbus: the area where the cornea meets the sclera
iris: colored part of the eye; regulates the amount of light entering the pupil
pupil: the opening of the eye
ciliary body: contains the ciliary muscle which controls eye movements
choroid: contains capillary network supplying blood to the retina
anterior chamber: space between iris and cornea
aqueous humor: the liquid found in the anterior and posterior chambers
vitreous humor: a clear & gelatinous; helps maintain the shape of the eye; gives support to the retina
retina: the area of the eye a light image is formed
fovea: contains photoreceptors cells called cones
cones: one of the two photoreceptor cells
optic disk: the location of the "blind spot" where no photoreceptors are located
optic nerve: carries impulses to the brain
balance: ears contain receptors to hear and __________.
pinna: the visible portion of the ear
auditory canal: the external _______ _________ channels sound waves toward the middle ear
eardrum: the tympanic membrane is also known as this
Eustachian: this tube ensures that equal air pressure exists on both sides of the tympanic membrane.
ossicles: the malleus, incus, and stapes are the auditory ________ found in the middle ear.
vestibulocochlear: the nerve that sends impulses to the brain for interpretation
