Flashcards in Review Deck (46):
1

reflex contraction to loud sound

tensor tympani, stapedius

2

innervates malleus

trigeminal nerve

3

innervates stapes

facial nerve

4

basilar membrane is thin but blank and hears blank frequency

stiff

5

apex hears blank frequencies and is wide and blank

low, flexible

6

hair cells

stereocilia

7

inner hair cells have blank rows, and transmit signals to blank

one, auditory nerve

8

outer hair cells have blank rows and is for blank

3, electromotility (wiggle up and down)

9

damage to hair cells or auditory nerve fibers

sensorineural hearing loss

10

deflection of stereocilia --> tip links open ion channels --> hair cell depolarizes --> activate auditory nerve fibers --> signal sent to brain

inner hair cell

11

deflection of stereocilia --> tip links open ion channels --> hair cell depolarizes --> change in cellular shape and amplifies basilar membrane

outer hair cellsr

12

central auditory pathway

cochlear nucleus, superior olivary complex, inferior cooliculus, medial geniculate body, auditory cortex

13

medial geniculate body is in the blank

thalamus

14

vestibular system for angular motion

semicircular canals

15

vestibular system parts for linear acceleration

utricle, saccule

16

semicircular canals are aka

ampula

17

utricle saccule is aka

macula

18

sensitive to light, easily bleached, and concentrated in periphery

rods

19

cones are not very active in dim light, for color vision, blank, and concentrated in blank

acuity, fovea

20

two photoreceptors

rods, cones

21

right visual field is processed in the blank and blank

right nasal, left temporal

22

blank crosses at optic chiasm

nasal

23

go over that visual diagram with lesions too

ok

24

parvo cellular?

k

25

what? color?

ventral stream

26

movement? how?

dorsal stream

27

glomerulus has dendrites from blank cells

mitral

28

olfaction diagram

ok

29

primary olfactory cortex

pyrifom/entorhinal cortex

30

superficial slow adapting mechanoreceptors

merkel

31

superficial fast adapting mechanoreceptors

meissner

32

deep slowly adapting receptors

ruffini

33

deep fast adapting mechanoreceptors

pacinian

34

muscle spindles respond to blank

stretch

35

bundle of thin muscle fibers entwined by sensory fibers

spindle

36

know somatosensory pathway

ok

37

little dude pics

ok

38

know functions of cranial nerves

cranial nerves

39

four bulbospinal pathways

tectospinal, rubrospinal, vestibulospinal,reticulospinal

40

neck motor neurons

tectospinal

41

motor neurons of distal arm

rubrospinal

42

balance

vestibulospinal

43

excites axial and leg extensors, inhibits motor neurons

reticulospinal

44

direct loops initiates blank

movement

45

indirect loops blank movement

smooth

46

tensor tympani aka

malleus
