Lobe of Cerebellum
Name the functional lobe of the cerebellum described
| Question | Answer |
|---|---|
| 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 |
