diencephalon Flashcards
lamina terminalis is where
the anterior neural tube closed
nucleus right above the optic chiasm
suprachiasmatic nucleus; has to do with circadian rhythm
mammillary bodies marks
the posterior edge of the hypothalamus
relationship between thalamus and midbrain
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
hypothalamic sulcus separates?
the hypothalamus from the thalamus
pineal gland locale
between the superior colliculi, superiorly. part of the diencephalon
pulvinar is part of the
visual system. its the big part on the posteromedial part of the thalamus
input layer of the cortex
layer 4
output layer of the cortex
layer 6
function of the subthalamus
relays sensory information (somatomotor zone ofthe diencephalon)
function of the epithalamus
regulation of circadian rhythms; linking olfacotry system to brainstem
function of the hypothalamus
coordination of ans with endocrine system; participation in visual pathway
anterior part of the pituitary is from
stomodeum, rathke’s pouch
posterior pituitary gets projections
from something in the brain
fornix shape (starts and ends where)
C shaped; projection from the hippocampus to the mamillary bodies
nucleus with stripes in it
lateral geniculate nucleus
thalamic nuclei are segregated by?
connection to other brain regions
some places that the thalamus gets its info from
limbic system, reticular formation, sensory inputs, cerebellum, basal ganglia
thalamus-cortex connections
cortical regions are connected to very specific thalamic nuclei
ventral posterior medial division of thalamus gets what info
sensory face
ventral posterior lateral division of thalamus gets what info
sensory body
lateral posterior division of thalamus gets what info
motor
relationship between thalamus and internal capsule
thalamus is always medial
striatum/corpora striatum
catch all term for layers in the internal cortex
