Lobe of Cerebellum

Name the functional lobe of the cerebellum described

QuestionAnswer
Especially important in stereotyped movements Spinocerebellum
Receives afferents from the cuneocerebellar tract Spinocerebellum
Afferents include the ventral and dorsal spinocerebellar tract Spinocerebellum
Receives afferents from the lateral cuneate nucleus Spinocerebellum
Includes the interposed nuclei (globose and emboliform) Spinocerebellum
Especially important in fine motor control Pontocerebellum
Receives afferents from nucleus dorsalis Spinocerebellum
Receives some climbing fibers Pontocerebellum
Disturbances may result in speech problems Pontocerebellum
Most of its afferents come from the cerebral cortex via reticular nuclei Spinocerebellum, Pontocerebellum
Receives climbing fibers from the inferior olivary nucleus Pontocerebellum
Affects the lower motor neurons through the rubrospinal tract Spinocerebellum, Pontocerebellum
Efferent fibers decussate in the superior cerebellar peduncle Spinocerebellum, Pontocerebellum
Functions may be affected by a lesion in the internal capsule Spinocerebellum, Pontocerebellum
Affects lower motor neurons through the rubrospinal and corticospinal tracts Spinocerebellum, Pontocerebellum
Receives afferents directly from the maculae Vestibulocerebellum
Oldest phylogenetic portion Vestibulocerebellum
Disturbances likely result in truncal ataxia and nystagmus (choose one best) Vestibulocerebellum
Roughly equivalent to the flocculonodular lobe Vestibulocerebellum
Roughly equivalent to the archicerebellum Vestibulocerebellum
Ganules cells of the cortex receive mossy fibers Vestibulocerebellum, Spinocerebellum, Pontocerebellum
Deep nuclei receive inhibitory stimuli from the purkinje cells Vestibulocerebellum, Spinocerebellum, Pontocerebellum
Cortical efferents are inhibitory to the deep nucleus Vestibulocerebellum, Spinocerebellum, Pontocerebellum
In general affect muscles on the same side of the body Vestibulocerebellum, Spinocerebellum, Pontocerebellum
Associated with the fastigial nucleus Vestibulocerebellum, Spinocerebellum
Affects the lower motor neurons via the lateral vestibulospinal tract Vestibulocerebellum,
Affects the lower motor neurons via the medial and lateral vestibulospinal tracts Vestibulocerebellum, spinocerebellum
Affects the lower motor neurons via the medial longitudinal fasciculus Vestibulocerebellum, Spinocerebellum
A lesion would likely result in nystagmus and truncal ataxia Vestibulocerebellum
Projects to the vestibular nuclei Vestibulocerebellum,
Includes the dentate nucleus Pontocerebellum
Generally influences muscle tone on opposite side of the body Pontocerebellum
Efferents terminate on the red nucleus Spinocerebellum, Pontocerebellum
