Cerebellum part 1

?

1. what is the paleocerebellum formed by? (spinal part)

  • The midline of the vermis and paravermis and surounding globus and embelliform nuclei
  • foolluculonodular and fastigal nucleus
  • most of the cerebellar parts with dendate nucleus
1 of 7

Other questions in this quiz

2. 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?

  • 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.
  • It affects the LM system bilaterally via descending vestibulo-spinal and reticospinal tracts
  • afferent fibres= From vestibula nuclei in pons and medulla to cortex of ipsilateral flocculo-nodular lobe
  • Efferent fibres= projects to fastigial nucleus which then goes to vestibular nuclei and reticular formation

4. Which of these statement are incorrect?

  • Efferent divisions = vestibular cerebellum and lateral hemisphere
  • Efferent fibres comes Superior cerebellar peduncles and fastigal nucleus in inferior cerebellar nucleus
  • Afferent division = spinocerebellar and pontocerebellar
  • Neocerebellum is the cerebral part and is the largest part but all embyologically the newest part

5. Which of theses is not an archicerebellum

  • Spinal Part
  • Flocculonodular lobe
  • Fastigial nucleus
  • Vestibular part
