Flashcards in Diencephalon Deck (13):
1

parts of diencephalon

epithalamus
subthalamus
hypothalamus
thalamus

2

epithalamus

posterior to thalamus
has pineal gland
and habenular nucleus

3

pineal gland

secretes melatonin in darkness

role in seasonal cycles

4

habenular gland

relay for info from basal nuclei and limbic system to reticular formation

5

subthalamus

inferior to thalamus
lateral to hypothalamus
medial to internal capsule

6

subthalamus role

determine appropriateness
-parkinsons

important part of basal nuclei circuits
-relay

7

thalamus

gateway to cereral cortex
relays all sensory pathways

also relays to basal nuclei, cerebellum, limbic system

has left and right side

8

division of thalamus

lateral, medial, anterior, posterior

9

geniculate nuclei

in thalamus
2x lateral - visual info
2x medial - auditory info

10

lateral geniculate nuclei

visual info

11

medial geniculate nuclei

auditory info

12

olfaction

only somotasensory info to bypass thalamus

13

internal capsule

3 parts
anterior, posterior, genu

relays info from thalamus
