    cerebrum, cerebellum, diencephalon
  2. Which of the following is the site of CSF production
    choroid plexus
  3. The pons contains
    tracts that link the cerebellum with the brain stem
  4. The dural fold that divides the two cerebellar hemispheres is the
    falx cerebelli
  5. Cerebrospinal fluid is produced and secreated by
    ependymal cells
  6. The primary purpose of the blood-brain barrier (BBB) is to
    isolate neural tissue in the CNS from the general circulation
  7. The centers in the pons that modify the activity of the respiratory rhythmicity centers in the medulla oblongata are the
    apneustic and pneumotaxic centers
  8. The final relay point for ascending sensory information that will be projected to the primary sensory cortex is the
  9. The establishment of emotional states is a function of the
    limbic system
  10. Coordination of learned movement patterns at the subconscious level is performed by
    the cerebellum
  11. The two cereberal hemispheeres are functionally different, even though anatomically they appear the same
  12. What are the three important function of the CSF
    • 1) cushioning delicate neural structures
    • 2) supporting the brain
    • 3) transporting nutrients, chemical messengers and waste products
  13. Which three areas in the brain are not isolated from the general circulation by the blood-brain barrier?
    • 1) portions of the hypothalamus where the capillary endothelium is extremely permeable
    • 2) capillaries in the pineal gland
    • 3) capillaries at the coroid plexus

    • facial vestibulocochlear glossopharyngeal vagus accessory hypoglossal
  15. Why can the brain respond to stimuli with greater versatility than the spinal cord?
    The brain can respond with greater versatility because it includes many more interneurons, pathways, and connections than the tracts of the spinal cord
  16. Breifly summarize the overall function of the cerebellum
    Adjusts voluntary and involuntary motor activities based on sensory information and stored memories of previous experiences
  17. The only cranial nerves that are attached to the cerebrum and the ______ nerves.

    In parkinson disease, the substantia nigra is inhibited from secreting the NT, dopamine, at the basal nuclei

    • 1) subconscious ontrol skeletal muscle contractions
    • 2) control of autonomic functions
    • 3) coordination of nervous and endocrine systems
    • 4) secretion of hormones
    • 5) production of emotions and drives
    • 6) coordination of autonomic and voluntary functions
    • 7) regulation of body temperature
    • 8) control of circadian rhythms
  20. Stimulation of which part of the prain would produte sensations of hunger and thirst?
    feeding and thirst centers of the hypothalamus
