Lecture 14 - Cerebellum

Question 1

Lobes of the cerebellum?

Answer 1

anterior, posterior, flocculonodular

Question 2

Fissures of the cerebellum?

Answer 2

primary fissure, postero-lateral fissure

Question 3

Neocerebellum?

Answer 3

pontocerebellar and olivocerebellar fibres - fine motor co-ordination (developed last)

Question 4

Palaeocerebellum?

Answer 4

spinocerebellar and olivocerebellar fibres - proprioception

Question 5

Achicerebellum?

Answer 5

vestibulocerebellar and olivocerebellar fibres - balance

Question 6

Ruberospinal system?/

Answer 6

red nucleus innervates lower motor neurons

Question 7

Extra pyrimidal system - route 1?

Answer 7

striatum -> globus pallidus external -> globus pallidus internal -> reticular formation -> lower motor neurons

Question 8

Extra pyramidal system -> route 2?

Answer 8

striatum -> substantia nigra (pars compacta and) pars reticulatar -> reticular formation -> lower motor neuron

Question 9

Intracerebellar nuclei?

Answer 9

collateral of all cerebellar cell types (ponotcerebellar, spinocerebellar, vestibulocerebellar, olivocerebellar); maps movements you do and corrects
