|
deep grey matter of cerebrum
|
basal ganglia- motor control
basal forebrain nuclei- memory claustrum-? amygdala- limbic |
|
|
basal ganglia- where, nuclei are called, what,
|
-deep withing cerebral white matter
-nuclei called corpus straitum -with cerebral cortex, control movement -receives input from cortical areas -start, stop, regulate voluntary movement -estimates passage of time |
|
|
caudate nucleus
|
basal ganglia that arches over thalamus
|
|
|
lentiform nucleus
|
basal ganglia that is lens-shaped
|
|
|
diencephalon
|
-thalamus
-afferent impulse in, organize and amplify, signals to cerebral cortex |
|
|
thalamus- where
|
-between optic chiasm and mammilary bodies
-pituitary gland projects inferiorly |
|
|
thalamus- how many nuclei
|
a dozen
|
|
|
thalamus- function
|
-main visceral control of body

|
|
cerebellum- where, what, lobes, regions, must receive?
|
-dorsal to pons and medulla
-smoothes and coordinates movement -maintains equilibrium -2 hemispheres, separated by fissures (ridges are folia) -anterior, posterior, flocculondular lobes -regions: cortex (gray), internal white matter, deep cerebellar nuceli (deep gray matter) -needs info on equilibrium, needs movement info |
