Flashcards in Ch. 18 Lec 3 - General & Special Senses Deck (70):
0

bones in the middle ear that transfer vibrations from the tympanic membrane to inner ear

ossicles

1

three ossicles

malleus, incus, stapes

2

middle ear muscle that inserts on the malleus

tensor tympani

3

middle ear muscle that inserts on the stapes

stapedius

4

part of ear that is a series of tubes and cavities

inner ear

5

two sections of the inner ear

vestibule (balance), cochlea (hearing)

6

inner ear layer that contains endolymph fluid

membranous labyrinth

7

inner ear layer that is the dense bone layer of the temporal and contains perilymph fluid

bony (osseous) labyrinth

8

structure that converts vibrations to sound

cochlea

9

cochlea contacts the stapes at the blank

oval window

10

three ducts of the cochlea

scala vestibuli, scala media, scala tympani

11

scala vestibuli is divided by the blank

vestibular membrane

12

scala media is divided by the blank

basilar membrane

13

organ of corti is found on the blank

basilar membrane

14

three parts of the organ of corti

hair cells, cranial nerve 8, tectorial membrane

15

mechanoreceptors with stereocilia in the organ of corti

hair cells

16

cochlear branch contacts hair cells in the organ of corti

cranial nerve 8

17

positioned right above hair cell stereocilia in the organ of corti

tectorial membrane

18

when the oval window vibrates, the blank moves

perilymph

19

the cochlear branch of blank carries auditory sensations

cranial nerve 8

20

auditory sensations go to the blank, then travels to through the blank, then is processed in the blank

medulla, thalamus, auditory cortex of temporal lobe

21

high sounds are detected by blank parts of cochlea

large

22

low sounds are detected by blank parts of cochlea

small

23

three parts of the vestibule

semicircular canals, utricle, saccule

24

the semicircular canals surround the semicircular blank

ducts

25

semicircular canals have a blank at base

ampulla

26

each ampulla has a blank which attaches to a cupula

cristae

27

a blank is in the utricle/saccule

maculae

28

the blank has hair cells

cupula

29

when head is rotated, fluid moves through blank and fluid moves the blank so the hair cells stereocilia blanks, then blank occurs

canals, cupula, bends, depolarization

30

the maculae consists of these two things

hair cells, otoliths

31

small calcium carbonate crystals that is in a gel like substance

otolith

32

when head orientation changes, gravity pulls on blank which moves blank which deforms hair cell blank and blank occurs

statoconia, otolith, stereocilia, depolarization

33

eyelids are also known as blank

palpebrae

34

eyelids functions are to

protect/lubricate

35

two parts of eyelids

tarsal glands, conjunctiva

36

oily secretions keep lids from sticking together in eyelid

tarsal gland

37

thin protective mucus membrane of eyelid

conjunctiva

38

two parts of conjunctiva

palpebral, bulbar

39

the conjunctiva stops at blank edge

corneal

40

produces tears

lacrimal apparatus

41

lacrimal apparatus consists of these three things

lacrimal gland, lacrimal punctum, lacrimal canaliculi

42

produces tears

lacrimal gland

43

drain tears in the lacrimal canaliculi

lacrimal punctum

44

three layers of eye

fibrous tunic, vascular tunic, neural tunic

45

two parts of fibrous tunic

sclera, cornea

46

white of eye and is dense and irregular ct

sclera

47

transparent layer of eye

cornea

48

three parts of vascular tunic

iris, choroid, lens

49

smooth muscles and pigments and controls size of pupil

iris

50

vascularized pigmented layer

choroid

51

layered proteins and refracts light

lens

52

vascular tunic regulates amount of blank

light

53

vascular tunic controls shape of blank

lens

54

neural tunic has these cells

receptor, bipolar, ganglion, amacrine

55

rods and cones that detect light are blank cells

receptor

56

neurons that synapse with receptor cells

bipolar neurons

57

cells that modulate communication between bipolar and ganglion cells

amacrine

58

these are very light sensitive and can not see color

rods

59

rods require blank light than cones

less

60

for color vision

cones

61

cones give blank image

sharper

62

there are blank types of cones

three

63

three regions of the retina

mucula lutea, fovea centralis, optic disc

64

area of no rods

macula lutea

65

area of most cones within macula

fovea centralis

66

blind spot

optic disc

67

two cavities of eye

anterior, posterior

68

posterior cavity contains blank fluid

vitreous

69

anterior cavity has blank fluid

aqueous
