25
Q

iris

A

controls pupil diameter (how much light enters eye)

26
Q

pupil

A

where light enters eye

27
Q

sensory (nervous) tunic

A

retina pigmented layer, retina neural (nervous) layer, photo receptors, bipolar cells, ganglion cells, optic disc (blind spot), rods/cones, macula lute, fovea centralis

28
Q

retina pigmented layer

A

absorbs extraneous light; provides vitamin A for photoreceptor cells

29
Q

retina neural (nervous) layer

A

detects incoming light rays, convert to nerve signals and transmit to brain

30
Q

photo receptors

A

outermost of retina

contains pigment molecules that react to light energy (rods and cones)

31
Q

bipolar cells

A

middle layer of retina

dendrites have synapses from rods and cones- information converges as visual signals to go to brain

32
Q

ganglion cells

A

innermost layer of retina

neuronal convergence continues; axons extend into and through optic disc

33
Q

optic disc (blind spot)

A

no photoreceptors; no image forms

34
Q

rods

A

function in dim light

blue on model

35
Q

cones

A

function in high intensity light and color vision

3 kinds- red, green, blue

red on model

36
Q

macula lutea

A

houses fovea centralis

37
Q

fovea centralis

A

area of sharpest vision- high concentration of cones

38
Q

anterior segment/ cavity

A

between lens and cornea

anterior chamber with aqueous humor- between iris and cornea

posterior chamber with aqueous humor- between lens and iris

aqueous humor- filtrate of blood plasma; circulation provides nutrients and oxygen to both lens and cornea, helps maintain chemical environment with anterior cavity of the eye

39
Q

posterior segment/ cavity

A

contains vitreous humor- fills space between lens and retina; maintain eye shape, support retina flush against back of eye, transmits light from lens to retina

40
Q

lens

A

focuses incoming light onto the retina; shape determines degree of light refraction

41
Q

outer ear

A

pinna (auricle), external auditory canal, tympanic membrane (eardrum)

42
Q

pinna (auricle)

A

protect entry into ear; direct sound waves into bony tube (external auditory canal)

43
Q

external auditory canal

A

connects pinna and eardrum- directs sound into ear

aka external acoustic meatus

44
Q

tympanic membrane (eardrum)

A

vibrates to transmit sound waves to middle ear

45
Q

middle ear

A

ear ossicles (malleus, incus, stapes), pharyngotympanic tube (eustachian tube, auditory tube), oval (vestibular) window, round (cochlear) window

46
Q

malleus

A

hammer- vibrates causing footplate of stapes to open into oval window

47
Q

incus

A

anvil- vibrates causing footplate of stapes to open into oval window

48
Q

stapes

A

stirrup- initiates pressure waves in fluid within closed compartment of inner ear

49
Q

ear ossicles

A

malleus, incus, stapes

allow sound to transmit through tympanic cavity

50
Q

pharyngotympanic tube, eustachian tube, auditory tube

A

pressure equalization

51
Q

oval (vestibular) window

A

amplify transmitted sound

52
Q

round (cochlear) window

A

allows fluid in cochlea to move

53
Q

inner ear

A

vestibule (saccule, utricle), semicircular canals (ampulla), cochlea (spiral organ of Corti, scala media, basilar membrane, vestibulocochlear nerve, sterereocilia/hairs, tectorial membrane

54
Q

vestibule

A

saccule, utricle

detect linear movements of head and static equilibrium of head

55
Q

semicircular canals

A

ampulla

detect rotational movement of the head

56
Q

cochlea

A

spiral organ of Corti, scala media, basilar membrane, vestibulocochlear nerve, sterereocilia (hairs), tectorial membrane

57
Q

spiral organ of Corti

A

hearing

58
Q

scala media

A

cochlear duct

extends through cochlea

59
Q

basilar membrane

A

movement of basilar membrane causes distortion of sterereocilia

60
Q

vestibulocochlear nerve

A

CN VIII

61
Q

sterereocilia (hairs)

A

long, stiff microvilli covering apical surface of hairs; sensory receptors for hearing release neurotransmitter to sensory neurons that monitor activity

62
Q

tectorial membrane

A

above sterereocilia
