    more complex
  5. The thin partition that separates the first and second ventricles is the:
    septum pellucidum
  6. What structure is covered by many blood vessels and adheres tightly to the surface of the brain?
    pia mater
  7. Cerebrospinal fluid:
    is secreted by ependymal cells
  8. Ependymal cells work to:
    • - adjust the composition of CSF
    • - surround the capillaries of the choroid plexus
    • - remove waste products from CSF
    • - secrete CSF into the ventricles
  9. The layer of the meninges that closely follows every gyrus and sulcus is the:
    pia mater
  10. The medulla oblongata regulates:
    blood pressure and respiration
  11. The cardiovascular reflexes are based in the:
    medulla oblongata
  12. Overseeing the postural muscles of the body and making rapid adjustments to maintain balance and equilibrium are functions of the:
    cerebellum
  13. The cerebellar hemispheres are separated by a band of cortex called the:
    vermis
  14. The presence of many large, highly-branched Purkinje cells in a sample of brian tissue indicates that it cam from the:
    cerebella cortex
  15. The medulla oblongata relays auditory information to the:
    inferior colliculi
  16. Nerve fiber bundles on the ventrolateral surface of the mesencephalon are the:
    cerebral penduncies
  17. The reflex movement of the head toward a loud noise is directed by the mesencephalon. Which nuclei accomplish this?
    inferior colliculi
  18. Which structure connects the left and right cerebral hemispheres?
    corpus callosum
  19. What structure secrets the hormone melatonin?
    pineal gland
  20. What are properties of the mamillary bodies?
    • - located in posterior hypothalamus
    • - shaped like little breasts
    • - control reflex eating movements
    • - process olfactory information
  21. What are the functions of the hypothalamus?
    • - secretes oxytocin
    • - produces ADH
    • - regulates body temperature
    • - controls autonomic centers

    are part of the limbic system
  23. The posterior nuclei of the thalamus include:
    lateral and medial geniculate nuclei
  24. What is the function of the thalamus?
    process sensory information and relay it to the cerebrum
  25. The _____ filters and relays sensory information to the cerebral cortex.
    thalamus
  26. What are properties of the limbic system?
    • - functions in emotions, learning, and memory
    • - located between the border of the cerebrum and diencephalon
    • - contains cerebral and diencephalic components
    • - links conscious functions of the cerebral cortex with unconscious functions of the brain
