diencephalon

Question 1

lamina terminalis is where

Answer 1

the anterior neural tube closed

Question 2

nucleus right above the optic chiasm

Answer 2

suprachiasmatic nucleus; has to do with circadian rhythm

Question 3

mammillary bodies marks

Answer 3

the posterior edge of the hypothalamus

Question 4

relationship between thalamus and midbrain

Answer 4

a lot of it overlies the midbrain with the superior colliculi, so when you cut it, often times you will see both parts in a section

Question 5

hypothalamic sulcus separates?

Answer 5

the hypothalamus from the thalamus

Question 6

pineal gland locale

Answer 6

between the superior colliculi, superiorly. part of the diencephalon

Question 7

pulvinar is part of the

Answer 7

visual system. its the big part on the posteromedial part of the thalamus

Question 8

input layer of the cortex

Answer 8

layer 4

Question 9

output layer of the cortex

Answer 9

layer 6

Question 10

function of the subthalamus

Answer 10

relays sensory information (somatomotor zone ofthe diencephalon)

Question 11

function of the epithalamus

Answer 11

regulation of circadian rhythms; linking olfacotry system to brainstem

Question 12

function of the hypothalamus

Answer 12

coordination of ans with endocrine system; participation in visual pathway

Question 13

anterior part of the pituitary is from

Answer 13

stomodeum, rathke’s pouch

Question 14

posterior pituitary gets projections

Answer 14

from something in the brain

Question 15

fornix shape (starts and ends where)

Answer 15

C shaped; projection from the hippocampus to the mamillary bodies

Question 16

nucleus with stripes in it

Answer 16

lateral geniculate nucleus

Question 17

thalamic nuclei are segregated by?

Answer 17

connection to other brain regions

Question 18

some places that the thalamus gets its info from

Answer 18

limbic system, reticular formation, sensory inputs, cerebellum, basal ganglia

Question 19

thalamus-cortex connections

Answer 19

cortical regions are connected to very specific thalamic nuclei

Question 20

ventral posterior medial division of thalamus gets what info

Answer 20

sensory face

Question 21

ventral posterior lateral division of thalamus gets what info

Answer 21

sensory body

Question 22

lateral posterior division of thalamus gets what info

Answer 22

motor

Question 23

relationship between thalamus and internal capsule

Answer 23

thalamus is always medial

Question 24

striatum/corpora striatum

Answer 24

catch all term for layers in the internal cortex

Question 25

striatum different from striate?

Answer 25

YES striate is somewhere else relating to the visual system

Question 26

medial hypothalamic zone fxns

Answer 26

hormones, circadian rhythms, body temperature, feeding, cardiovascular fxn

Question 27

lesions to subthalamic nucleus

Answer 27

hemiballismus; flailing of one half of the body; basal ganglia can’t control their mvmt adequately

Question 28

major blood vessels of the diencephalon

Answer 28

lenticulostriate(MCA), recurrent artery of heubner (ACA)

Question 29

anterior choroidal artery right next to

Answer 29

optic tract. if you have a problem here you can get deficits in the visual field like heminanopsias

Question 30

anterior nucleus of thalamus blood supply

Answer 30

thalamoperforating aa

Question 31

head of caudate gets blood from?

Answer 31

medial striate aa

Question 32

betz cells are in what layer

Answer 32

layer 5 of cerebral cortex

Question 33

prefrontal cortex function

Answer 33

its multimodal for excecutive brain restraint, initiative, and order

Question 34

optic radiations are where

Answer 34

in white matter of both the parietal and temporal lobes

Question 35

relationship between basal ganglia and cortex

Answer 35

they are directly connected

Question 36

relationship between the cereBELlum and the cortex

Answer 36

indirectly connected through the pons

Question 37

anterior perforated substance is from

Answer 37

this is because the lenticulostriate arteries are perforating the dorsal part of the brain to send blood supply to thalamus/basal ganglia/internal capsule

Question 38

short gyri of insula

Answer 38

related to disgust, olfactory, taste fxn.

Question 39

most of taste ends up?

Answer 39

in the insular cortex

Question 40

when you thing of GVA and SVA what do you think of

Answer 40

insular cortex

Question 41

three structures with a c shape

Answer 41

stria terminalis, fornix, caudate
