Cerebelleum Flashcards
The vermis and flocculonodular lobes are important for control of?
Proximal and trunk muscles, and VOR control
The intermediate part of the CB hemisphere is mainly involved in control of?
More distal appendicular muscles in the arms and legs
The lateral part of the CB hemisphere is involved with?
motor planning for extremities
All outputs from the CB are relayed by?
Deep cerebellar nuclei
Mossy fibers arise from?
numerous regions
Mossy fibers ascend through CB whit matter to form excitatory synapses on dendrites of?
granule cells
Granule cells send axons into the ______ which then bifurcate and form _____________?
Molecular layer, for parallel fibers.
All output from CB is carried by axons of the?
Purkinje cells
Purkinje cells from inhibitory synapses on?
Deep CB nuclei and vestibular nuclei
Climbing fibers arise exclusively from?
contralateral inferior olivary nucleus
Climbing fibers have a strong modulatory effect on Purkinje cells which in that it causes a _________?
sustained decrease in their response to synaptic inputs from parallel fibers
Basket cells and stellate cells are located in the?
Molecular layer
Basket cells and stellate cells are excited by synaptic inputs from?
granule cell parallel fibers
The lateral CB hemisphere projects to which deep CB nuclei?
Dentate
The Dentate nucleus projects via the _______ to reach the ________?
Superior CB peduncle, to reach the VL nucleus of the thalamus.
