Cerebellar Functional Modules Flashcards
Which components of the cerebellum are primarily responsible for regulating eye movements and modulating postural control through the vestibular system?
A. Vermis and interposed nucleus
B. Flocculonodular lobe and fastigial nucleus
C. Dentate nucleus and paravermis
D. Medial hemisphere and dentate nucleus
B. Flocculonodular lobe and fastigial nucleus
The vestibulocerebellum receives input from?
A. ipsilateral vestibular nerve and nuclei & contralateral AON
B. Dentate nucleus and paravermis
c. Vermis and interposed nucleus
A. ipsilateral vestibular nerve and nuclei & contralateral AON
The vestibulocerebellum receives ouput from?
A. ipsilateral vestibular nerve and nuclei & contralateral AON
B. Dentate nucleus and paravermis
c. flocculonodular lobe to ipsilateral vestibular nuclei (regulates eye
movements) & fastigial nucleus
c. flocculonodular lobe to ipsilateral vestibular nuclei (regulates eye
movements) & fastigial nucleus
The spinocerebellum receive input primarily from ipsilateral proprioceptive information and contralateral anterior olivary nucleus (AON). What is the components of the output contributing to the ventromedial system and there function?
A. Output: Medial zone to fastigial nucleus
Function: Modulation of postural control and trunk region of the premotor cortex (PMC) through the ventromedial system.
B. Output: Ipsilateral proprioceptive information & contralateral AON
Function: Modulation of limb regions of the premotor cortex (PMC) and the red nucleus through the dorsolateral system.
C. Output: Dentate and fastigial nucleus
Function:Modulation of eye movement region of the premotor cortex (PMC) through the ventromedial system.
A. Output: Medial zone to fastigial nucleus
Function: Modulation of postural control and trunk region of the premotor cortex (PMC) through the ventromedial system.
The spinocerebellum receive input primarily from ipsilateral proprioceptive information and contralateral anterior olivary nucleus (AON). What is the components of the output contributing to the dorsolateral system and there function?
A. Output: Intermediate zone to interposed nuclei
Function: Modulation of limb regions of the premotor cortex (PMC) and the red nucleus through the dorsolateral system.
B. Output: Dentate and fastigial nucleus
Function:Modulation of eye movement region of the premotor cortex (PMC) through the ventromedial system.
C.Output: Medial zone to fastigial nucleus
Function: Modulation of postural control and trunk region of the premotor cortex (PMC) through the ventromedial system.
A. Output: Intermediate zone to interposed nuclei
Function: Modulation of limb regions of the premotor cortex (PMC) and the red nucleus through the dorsolateral system.
The cerebrocerebellum primarily receive input from the contralateral sensorimotor cortices via relay in the pons (pontine nuclei), as well as contralateral anterior olivary nucleus (AON), what components constitute as the output?
A. Medial zone and fastigial nucleus
B. Intermediate zone and interposed nuclei
C. Lateral zone and dentate nucleus
D. Vermis and flocculonodular lobe
C. Lateral zone and dentate nucleus
Function: Dentate nucleus modulates UMN of the motor cortices and red nucleus =
modulation of dorsolateral system.
