Cerebellum part 1

HideShow resource information

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

3. Which of these statements of the tracts to the archicerebellum is incorrect?

  • Efferent fibres= projects to fastigial nucleus which then goes to vestibular nuclei and reticular formation
  • 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
  • It affects the LM system bilaterally via descending vestibulo-spinal and reticospinal tracts

4. Which of these statement are incorrect?

  • Efferent fibres comes Superior cerebellar peduncles and fastigal nucleus in inferior cerebellar nucleus
