helps see in low light situations

Front 20

cones

Back 20

help us see colo and sharper,clear

Front 21

filling the posterior cavity of the eye is a jelly like substance called

Back 21

vitreous(maintains normal shape of eyeball)

Front 22

on the back of the retina is a samall disc called

at the center of the structure is a depression called the

Back 23

fovea centrailis

Front 24

on region of the retina that lacks photo receptors is called

Back 24

optic disk(blind spot)

Front 25

way in which to remeber the layers in the back of the eye Scared Cat Run

Back 25

-sclera
-choroid
-retina

Front 26

ear is divided into three regions

Back 26

-inner ear
-middle ear
-external ear

Front 27

external ear

Back 27

extends from ear to tympanic membrane

Front 28

auricle

Back 28

is made of elastic cartilage and directs sound waves into the external auditory meatus

Front 29

tympainic membrane(ear drum)

Back 29

cone shaped connective tissue vibrates when sound waves strike it

Front 30

middle ear

Back 30

air filled space that extends medial to tympanic membrane and up to the inner ear. it contains three ear ossicles, malleus,inus, and stapes

Front 31

the auditory or eustachian tube

Back 31

connects the middle ear to the nasopharynx

Front 32

this tube is shortand horizontal in childern and iteaiser for childeren it eaiser for bacteria to enter the middle

Back 32

nasopharynx

Front 33

inner ear

Back 33

is a bony complex of fluid filled chambers that contain recetors for hearing and equilibrium

Front 34

receptor for equilibrium are located

Back 34

semicircular canals

Front 35

receptors for hearing are located in the

Back 35

cochlea

Front 36

ear ossicles vibrate and transfer vibrations to

Back 36

oval window of the inner ear

Front 37

when a shock wave is sent through fluid filled chambers with in the cocchlea which eventually dissipate out throught the round window to the air in the

Back 37

typanic cavity

Front 38

this vibration stimulates hair cells in the
