The flashcards below were created by user kjsummers on FreezingBlue Flashcards. What would you like to do?


  1. What are the three parts of the Brainstem?
    1)
    2)
    3)
    • 1- midbrain
    • 2- pons
    • 3- medulla
  2. What is a collection of nuclei?
    Thalamus
  3. What is a collection of ganglia in close communication with the cortex?
    Basal Ganglia
  4. What is functionally involved with the grading of movement and adjusting movement strategies?
    cerebellum
  5. involved with eye movement and balance

    lesions in this area can produce problems in gait and conjugate eye movements
    Vestibulocerebellum
  6. involved with the control of the trunk and proximal muscles of arms and legs
    spinocerebellum
  7. grading of movements and adjusting movements to meet the task demands
    pontocerebellum ( cerebrocerebellum)
  8. what four nuclei receive both inhibitory and excitatory input?
    • Dentate
    • fastigial
    • emboliform
    • globose

    interpositus- emboliform and globose
  9. Three cerebellar peduncles which contain the afferent and efferent fibers
    • superior peduncle
    • middle peduncle
    • inferior peduncle
  10. major pathway for output of the cerebellum to other structures. 

    efferent fibers go to red nucleus, thalamus and medulla

    premotor cortex to support motor planning
    superior peduncles
  11. comprised of afferent fibers projecting into the cerebellum from the sensory and motor regions of the cerebral cortex, the largest of cerebellar peduncles
    Middle peduncle
  12. carries both afferent and efferent fibers involved with integrating proprioceptive information
    inferior peduncle
  13. contains the dendritic branches of the purkinje cells along with stellate and basket cells
    outer molecular layer of the cerebellar cortex
  14. cell bodies of the purkinje cells, this layer is sometimes refered to as the prkinje layer
    middle portion of cerebellar cortex
  15. contains granule cells and often is labeled as the Granular layer
    inner layer of cerebellar cortex
