Cerebellum part 1

1. Which efferent tract of the Paleocerebellum?

the corticol fibres goes to the globose and emboliform nuclei then to the red nucleus in the midbrain via superior cerebellar peduncles to then form the descending rubrospinal tracts
projects to fastigial nucleus which then goes to vestibular nuclei and reticular formation
dentate nucleus to the red nucleus and the ventral lateral nucleus of the thalamus to the motor cortex of frontal lobe which then forms the corticospinal and corticobulbar pathways

1 of 7

Dorsal and ventral spinocerebellar tracts from muscles, joints and cutaneous receptors enters cortex ipsilateral via inf. and sup. cerebellar peduncles
from cerebral cortex (planning of movement) to pontine nuclei. Goes contralateral via the middle cerebellar peduncle to end in lateral parts of the cerebellum (cortico-ponto-cerebral tract)
dentate nucleus to the red nucleus and the ventral lateral nucleus of the thalamus to the motor cortex of frontal lobe which then forms the corticospinal and corticobulbar pathways
From vestibula nuclei in pons and medulla (vestibullar apparatus from the inner ear) to the cortex ipsilateral to fluccolonodular lobe via vestibulocerebellar tracts

Efferent fibres= projects to fastigial nucleus which then goes to vestibular nuclei and reticular formation
It affects the LM system bilaterally via descending vestibulo-spinal and reticospinal tracts
Afferent = Dorsal and ventral spinocerebellar tract from muscle and joint and cutaneous receptors to enter the cortex ipsilaterslly from vermis and paravermis via inf. and sup. cerebellar peduncles.
afferent fibres= From vestibula nuclei in pons and medulla to cortex of ipsilateral flocculo-nodular lobe

most of the cerebellar parts with dendate nucleus
The midline of the vermis and paravermis and surounding globus and embelliform nuclei
foolluculonodular and fastigal nucleus
