balance (head orientation)
hearing

3

tongue

taste

4

nose

smell

5

touch

skin

6

what makes dendrites depolarize?

receptors

7

photo receptor

depolarizes with light
vision

8

chemo receptors

depolarizes with chemicals
taste and smell

9

mechanoreceptors

hearing and any physical movements

10

noci

pain

11

thermal

temperature regulation

12

baro

pressure (blood)

13

proprio

spacial orientation

14

meisners

light/touch

15

pacinian

pressure (touch)

16

ruffini

when skin is being stretched

17

markels

3D shapes

18

what is the scientific word for taste

gustation

19

papillae

adds surface area to tongue
attaches to cranial nerve

20

gustatory bud
taste bud

between papillae
depolarize chemicals we eat

21

taste pore

hole at top of taste bud

22

taste hair

protein

23

gustatory cell characteristics

hooked to neuron and have dendrites

24

support cells do not have

dendrites

25

cranial nerve 7

facial

26

cranial nerve 9

glossopharingeal

27

umami

savor taste
depolarize w glutamic acid (glucose)

28

salt

sodium chloride

29

majority of senses are

bipolar

30

olfaction

smell (gas)

31

support cells are

ciliated pseudostratified columnar epithelium

32

olfacorty neurons

bipolar neurons

33

cubiform plate

where olfactory nerves travel through

34

after olfactory nerves travel through, they go where

synapse on olfactory bulb

35

olfactory bulb goes to the

olfactory tract

36

olfactory tract makes up

cranial nerve 7

37

what is the one sense that doesn't go to the thalamus

olfactory

38

papillae are made up of

taste bud and epithelial tissue

39

every taste bud has a whole, and it's called

a taste pore

40

what is the taste hair for

to trap saliva baring the chemicals
slows it down so it can be absorbed

41

what is the taste all over the tounge?

umami

42

eyelid

keeps eye moist and for protection

43

eyelash

protects eye from air and dust

44

sty

subacious gland that's inflammed

45

conjunctiva

gap of tissue on eye socket

46

conjunctivitis

pink eye

47

tunics of eye

fibrous layer
vascular/choroid layer
nervous tunic/retina

48

fibrous layer

outside layer

49

what are the parts of the fibrous layer of the eye

sclera: white part of eye
cornea: clear covering of the iris and retina: images can come thru

50

vascular/choroid layer parts

ciliary body
ciliary process: suspensory ligament, lens

51

ciliary muscle

iris

52

nervous tunic/retina

clear ball

53

fovea centralis

area of highest concentrations of rods and mainly cones

54

lens

sacs of clear protein

55

what is inside the macula lutea

fovea centralis

56

optic disc

blind spot

blood supply of eye

57

cavities of the eye

posterior (vitreous)
anterior/aqueios cavity

58

posterior (vitreous)

vitreous humor
thick fluid
shape of eyeball

59

anterior (aqueous) is more

waterlike

60

vitreous humor

thick fluid of eye

61

what produces aqueous humor

ciliary process

62

chambers of the eye

anterior: cornea to iris
posterior: iris to lens

63

canal of schlemm

reabsorb aqueous humor

64

glaucomma

build of aqueous humor because it isn't absorbed by canal of schlemm

65

anopsia

unable to see

66

myopsia

near sided

67

hyperopsia

far sided

68

-opsia

vision

69

blepharitis

reoccuring infection of the eyelid

70

trachoma conjunctivitis

reoccurring pink eye

71

achromatopsia

color blindness

72

astigmatism

ridges that obstruct vision on cornea

73

lysozyme

enzyme found in tears to break down antigens

74

what is lysozyme absorbed by

lacrimal canal

75

dendritis in eyeball are only in where

retina

76

dendrites start what

depolarization

77

why is it called a blind spot

optic nerve is an axon, so when light hits it, it can't depolarize the light

78

the further you get from fova centralis

less dendrites

79

cateracs

sun spots on lens

80

iris

pigmented muscle

81

oliptical shaped eye

myopsia

82

flat shaped eye

hyperopsia

83

Senses

eye
ear
tongue
nose
touch

84

rods

light

85

cones

color

86

pressure from aqueous humor on the cornea and the lens

glaucoma

87

what reabsorbs aqueous humor

canal of shalamm
