Cl channels

2

mesencephalon

midbrain

3

prosencephalon

forebrain

4

proseencephalon becomes what

telencephalon and diencephalon

5

diencephalon becomes what

thalamus
hypothatlamus and retin

6

telecephalon becomes what

cerebral Cx and basal ganglia

7

rhombencephalon becomes

metencephalon and myelencephalon

8

metecephalon becomes

cerebellum and pons

9

myelencephalon becomes

medulla

10

CN derived from what parts of brain

1:1:2:2:6
I telencephalon
II diencephalon
III IV mesencephalon
V VI metencephalon
VII VIII IX X XI XII myelencephalon

11

4 major sulci of brain

central- sulcus rolando
lateral sulcus- sylvian fissure
parietoociipital sulcus
cingulate sulcus
preoccipital notch

12

cingulate sulcus

around corpus callosum

13

gyri in frontal lobe

superior middle and inferior
precentral gyrus
orbital part triangular part and opercular part
part of paracentral lobule
orbital gyri, olfactory bulub

14

brocas aphasia locaiton

opercular part of frontal lobe
brocken speech

15

lobes in pareital

post central gyrus
supramarginal gyrus
angular gyrus
posterior paracentral lobule
precuneus

16

R side parietal lesions

hemineglect
L side does not exist

17

where in the world we are?

pareietal lobe

18

lobes temporal lobe

superior middle inferior
limbic gyrus
fusiform gyrus

19

wernickes aphasia location

superior temporal lobe
fluent aphasia

20

lobes in occipital lobe

lateral occipital gyri
lingual hyrus
cuneus
calcarine sulcus
fusiform gyrus

21

lingual gyrus visual field

superior

22

cuneus visual field

inferior

23

limbic lobe

isthmus, collateral sulcus, parahippocampal gyrus, rhinal sulcus, uncus, subcallosal area, paraterminal gyrus
cingulate sulcus and gyrus

24

fear aggression

amygdala

25

center of telencephalon

basal ganglia
thalamus
internal capsule

26

role basal ganglia

smooth out movements

27

separates the thalamic nuclei

internal medullary lamina

28

3 divisions nuclei in thalamus

anterior
medial
lateral (dorsal/ventral)

29

what shuts down input of sensory like whne sleeping

thalamic reticular system

30

patterns for hypothalamic control

anterior (PAN)
posterior (SAN)
neuroendocrine
bi-directional circuitry
controls reticulospinal system

31

rostral hypothalamic lesion vs caudal

rostral never sleep
caudal never wake up

32

where are the inferior and superior colliculi

midbrain
superior-vision/eye control
inferior- hearing

33

crus cerebri

cerebral pedunceles

34

pain modulation

periaqueductal grey

35

lesion in inferior colliculi

inability to localize sound because auditory pathway bilateral

36

VTA

ventral tegmental area
release dopamine to nucleus accumbens
"i want or I need"

37

pons parts

tegmentum and basal pons

38

what is in pons

locus ceruleus
micturition center
CN nuclei
reticular formation

39

locus ceruleus

secrete Epi and Norepi

40

cerebellum

proprioception input
coordinates complex movements

41

roles of medulla

resp center
cardiac center
consciousness center
pathway for all ascneding descending information
CN nuclei

42

DCML

sensory two point discrimination
vibration
proprioception

43

where are cell bodies for DCML

DRG

44

where DCML enter spinal cord

dorsal faniculus and ascends to medulla

45

decussation DCML

in medulla- internal arcuate fasiculus
runs up in medial lemniscus here on up

46

secondary neurons of DCML synapse where

thalamus VPL
than goes to primary sensory Cx

47

types of DCML

cuneatus more lateral: limbs
and gracilus: more medial, trunk

48

Anterolateral system
sensory

pain
temp
crude tough

49

cell bodies ALS

dorsal route

50

where does ALS pathway enter

lisour fasciculus ascends then synapses in dorsal horn

51

decussation ALS

anterior white commisure

52

tract ALS runs in

antero lateral spinothalamic pathway to VPL thalamus

53

ion channels on pacinian corpuscles

TRP channels

54

4 spinocerebellar tracts
unconscious proprioception

fine: cuneocerebellar upper half body
rostralspinocerebellar (don't need to know)
dorsal(fine movement) and ventral (gross) spinocerebellar tracts

55

ventral spinocerebellar tract decussation

decussates twice so is ipsilateral

56

ventral trigeminothalamic tracts

nociceptive info of head
