Cerebellum Flashcards
This plays a role in planning and initiation of movement
Pontocerebellum
Spinocerebellum is for synergy (control rate, force, range, direction of movement)
____ is the failure to perform rapid alternating movements
dysdiadochokinesia
____ is a low frequency tremor whose amplitude increases as an extremity approaches the endpoint of deliberate and visually guided movement
Intention tumor
_____ phenomenon is the failure of antagonistic muscle to contract after removal of resistance to limb movement
Absent rebound phenomenon
The purkinje cell layer is the only output of the cerebellar cortex which uses ____ NT
GABA, inhibitory.
Output projects to deep cerebellar nuclei and to the vestibular nucleus
The granulate cell excites basket and stellate cells. It uses ___ as NT.
Glutamate
The basket cells inhibit purkinje cells by releasing
GABA
This cell releases GABA to inhibit the deep cerebellar nuclei
purkinje cells
The ___ and ____ fiber inputs exert a strong excitatory effect on purkinje cells
