Cerebellum

  • Cells present in cerebellum are Purkinje cells, Stellate cells & Basket cells
  • Neocerebellum is concerned with Motor planning 
  • Nucleus dentatus, Nucleus globosus & Nucleus fastigii are nuclei of cerebellum
  • Lesions of the lateral cerebellum cause Incoordination, Intention tremor & Ataxia
  • Purkinje cells from the the cerebellum end in Cerebellar nuclei
  • Efferent tracts from cerebellum arisen from Deep cerebellar nuclei
  • Vestibulocerebellar tract terminates in the Flocculus, Nodulus & Uvula of cerebellum
  • By three cerebellar peduncies, the cerebellum is attached to Medulla
  • Output from the cerebellum is solely from Purkinje cells
  • True about cerebellum Co-ordination, Planning of motor movements
  • Dentate nucleus is a part of Cerebellum
  • Cerebellum has 3 layers, 4 nucleus & 5 cells
  • Cerebellum Climbing fibres are afferent inputs
  • Cerebellum Climbing fibres excite Purkinje cells
  • Smoothness and coordinates ongoing movements states the role of cerebellum in motor performance
  • Most common site for medulloblastoma is Cerebellum
  • Posture, Equilibrium & Tone are affected in damage to cerebellum
  • Intention tremors are seen in lesion of Cerebellum
  • Function of floccunodular lobe of cerebellum is Equilibrium
  • walking or standing, posture is maintain by Cerebellum
  • Feed forward inhibition synapse seen in Cerebellum
