  1. What are the three parts of the brain stem?
    • Midbrain
    • Pons
    • Medulla oblongata
  2. Describe the midbrain.
    • Contains nuclei that coordinate visual and auditory reflexes.
    • Contains centers that help to maintain consciousness.
  3. Describe the pons.
    • Connects cerebellum to brain stem.
    • Has tracts and relay centers.
    • Contains nuclei that function in somatic and visceral motor control
  4. Describe the medulla oblongata.
    • Relays sensory information to other areas of brain stem and thalamus.
    • Contains major centers that regulate autonomic function.
  5. Describe the structure of a ventrivle of the brain.
    • Cavity filled with cerebrospinal fluid.
    • Lined with ependymal cells.
    • Connected by narrow canals.
  6. Describe the structure and location of the Lateral centricles.
    • Contained within each cerebral hemisphere.
    • Each connected to third ventricle by interventricular foramen.
    • Separated medially by septum pellucidum.
    • “Roof” partially formed by thick white matter tract connecting hemispheres (corpus callosum).
  7. Describe the structure and location of the third ventricle.
    • Contained within diencephalon.
    • Connected to fourth ventricle by aqueduct of the midbrain (cerebral aqueduct).
  8. Describe the structure and location of the fourth ventricle.
    • Between pons of brain stem anteriorly and cerebellum posteriorly.
    • Continuous with central canal of spinal cordcerebral aqueduct connects it to third ventricle.
