Q

how often are olfactory neurons replaced?

A

every 1-2 months

18
Q

where are the first cells in the olfactory pathway?

A

olfactory epithelium

19
Q

what causes nystagmus?

A

the hairs of the cristae are bent while the endolymph is still spinning (inertia)

20
Q

kind of equilibrium: body is still, head is in motion

A

static

21
Q

what kind of receptors are the vestibular hair cells?

A

mechanoreceptors

22
Q

what kind of receptors are involved in olfaction?

A

chemoreceptors

23
Q

what part of the vestibular apparatus is responsible for static equilibrium?

A

utricle and saccule

24
Q

what neurotransmitter is released when an AP is generated by the hair cells?

A

glutamate

25
Q

what kind of brain waves are seen during non-REM sleep?

A

delta

26
Q

The receptors for dynamic equilibrium are called…

A

cristae ampullaris

27
Q

what do the hair cells in the macula attach to?

A

CN VIII

28
Q

awareness of the position of the body and limbs in space

A

proprioception

29
Q

how many semicircular canals are in the vestibular apparatus?

A

3

30
Q

What is the substance in the semicircular canals that will lag behind due to inertia?

A

endolymph

31
Q

what structure allows the olfactory nerves to pass through it?

A

cribriform plate

32
Q

which stage of non-REM sleep is often called “slow-wave” sleep?

A

stage 3

33
Q

pain pathway: highly localized and very rapid. carries info to the thalamus

A

lateral spinothalamic

34
Q

what is the only sense that is processed in the limbic system, rather than going to the thalamus?

A

olfaction

35
Q

what kind of sensory receptor is activated by the release of chemicals from damaged tissues?

A

nocireceptors

36
Q

When the endolymph in the semicircular canals lags behind, what happens as a result?

A

cupula lags and hairs are bent > AP in vestibular neurons

37
Q

what kind of brain waves are seen during REM sleep?

A

theta

38
Q

Each macula has __________: the tips are anchored to gelatinous block containing crystals called _______

A

hair cells; otoliths

39
Q

kind of equilibrium: body is in motion, head is still

A

dynamic

40
Q

which type of sleep is restorative and is associated with memory storage?

A

non-REM sleep

41
Q

how do you assess vestibular functioning (possibly in a case of nystagmus)?

A

cold caloric test

42
Q

where are the hair cells located that detect changes in motion and position of the head?

A

vestibular apparatus of the inner ear
