all of the following are tunics that compose the wall of the eye except -sensory -choroid -fibrous -all of the above are tunics

all of the above are tunices

all of the following are tunics that compose the wall of the eye except -allow for light to pass through -repair itself bc its easily damaged -most exposed part of the eye -allow for detailed color vision

allow for detailed color vision

Fluid that fills the anterior (front) chamber of the eye

aqueous humor

the nerve that transmits nerve impulses from the cochlea to the brain

auditory nerve

the smallest bones in the body. they transmit sound vibrations across the middle ear

auditory ossicles

area of the retina that lacks rods and cones

blind spot

coating that provides nutrients to eye. becomes the iris in the front of the eye

choroid

heavily pigmented coating that prevents light scattering within the eyeball: reflects light in nocturnal animals

choroid

sound vibrations are converted here into electrical impulses

cochlea

which of the following is not a sense we have for our bodies? -hearing -equilibrium -taste -common

common

the delicate membrane that covers the front of the eyeball

conjunctiva

most anterior part of the sclera - the window on to the world

cornea

this canal can harbor mites in cats and dogs

ear canal

connects the pharynx (throat) and the middle ear to keep the air pressures equal

eustachian tube

true or false: at birth, babies are near-sighted because their eyeballs are too large

false

true or false: color blindness is caused by excess cones

false

true or false: dynamic equilibrium is referring to straight line movements of the head and means "at rest"

false

true or false: glaucoma is an eye disorder that effects young people more often than the elderly

false

true or false: human has monocular vision, which allow us to have depth perception and see things in three dimensions.

false

true or false: internal eye muscles are controlled by the somatic, not autonomic, nervous system

false

true or false: the pupil is the pigmented layer that gives the eye color

false

how many taste receptors do we have?

five (sweet, sour, bitter, salty, umami)

area of the retina of most detailed vision

fovea

Which of the following is not a function of lacrimal fluid to the eye -protect -heal -moisten -lubricate

heal

the part of the ear consisting of the cochlea and the vestibular organ

inner ear

colored structure that controls the size of the pupil

iris

which of the following structures do not contain photoreceptors -iris -rods -cones -all of the above contain photoreceptors

iris

the part of the ear that contains the ear (auditory) ossicles

middle ear

the third eyelid

nictitating membrane

the nerve that takes nerve impulses from the retina to the brain

optic nerve

animals can turn this towards the direction of the sound

pinna

aperture of the eye. where the light enters

pupil

bright light causes what to constrict

pupil

layer containing the rods and cones

retina

outer coating of tough, fibrous connective tissue

sclera

the white of the eye

sclera

what two senses complement each other the best

taste and smell

how many tunics, or coats, compose the wall of the eye

three

there are how many types of cones for vision?

three

which of the following senses is not housed in the ear? -hearing -equilibrium -touch -all of the above are found in the ear

touch

true or false: all special senses are functional at birth, except vision because years of "learning" are still needed

true

true or false: bitter taste receptors help protect us from ingesting poisons and spoiled foods

true

true or false: cataracts occurs when the lens becomes increasingly hard and opaque

true

true or false: earwax is produced in the ceruminous glands of the outer ear.

true

true or false: fibers of each eye cross at the optic chiasma before they connect to the thalamus in the brain?

true

true or false: only 1/6 of the eyes surface is actually exposed

true

true or false: presbyopia is an eye condition that basically causes far-sightedness in elderly people

true

true or false: the sclera is seen as "the white of the eye" and found in the fibrous tunic

true

true or false: viewing very close objects causes convergence ( cross-eyed effect)

true

how many functional parts does equilibrium have?

two (static and dynamic)

vibrates as sound waves hit it. transmits these vibrations to the auditory ossicles

tympanic membrane

contains receptors for the sense of balance and movement

vestibular organ

jelly-like substance filling the posterior cavity of the eyeball

vitreous humor
