Q: Treatment of cancer or infections in the central nervous system are hampered by
the inability of most drugs to cross the blood-brain barrier. What would be the
dangers of altering the blood-brain barrier so that drugs could more easily enter
the central nervous system?
Answer:
The composition of the CSF would change and more closely resemble plasma, and
bacteria and viruses might more easily enter the CNS.

Q: The rabies virus, caused by the bite of an infected animal, is capable of entering
the victim's
Answer:
brain. Propose a mechanism for this to happen. Several possibilities exist: Rabies
virus
particles might be able to bind to the surface of epithelial cells and then be
pinocytosed into
the cell and into the CSF. This is unlikely since the epithelium forming the BBB is
incapable of
pinocytosis.If the rabies virus particle was hydrophobic in nature it might be able to
pass
through the BBB directly. Again, if the viral particle was hydrophobic, it wouldn't be
able to pass
easily though blood. Alternatively, it can infect peripheral nerve axons and enter the
CNS by
retrograde transport to the cell bodies of afferent or efferent neurons, which is hoe it
enters
the CNS to multiply.

Q: Which of the following allows the anterior and posterior portions of the brain
and the spinal cord to still receive blood if one path is blocked?
Answer:
circle of Willis anterior communicating artery vertebral artery internal carotid artery
circle of Willis
Q: Would a blood clot in the right internal carotid artery always cause a stroke
within the brain?
Answer:
No; the interconnections between blood vessels within the brain would continue to
provide blood flow.
Q: Which of the following are found in the white matter visible in the central
nervous system?
Answer:
neuronal cell bodies unmyelinated axons myelinated axons glial cells myelinated
axons
