Explain how PET scans differ from CT scans. What are they useful for? - CORRECT
ANSWER✔✔- CT or CAT is an abbreviation for computerized axial tomography. These
scans provide medium-resolution images of the living brain by sequential X-rays of the brain
taken in an arc around the head. The many individual X-ray images are then mathematically
combined to provide an anatomical map of the brain. They are useful for visualizing strokes,
tumors, or cortical shrinkage. Positron emission tomography, or PET scans provide maps of
brain activity during a behavioral task. Radioactively labeled substances such as glucose are
injected into the bloodstream while a person engages in a cognitive task. As the most active
brain regions selectively take up the radioactive glucose, PET provides a moment-to-moment
color-coded map of brain activity. Oncology is one example for PET.
4 Points - Need to know the difference between them. Similar processes both are using the
same acquisition tomography (1). CT has an X-ray source that is moved around the patient
(1), PET the signal comes from within you in the form of gamma rays emitted from the
annihilation of a positron and an electron (1). Name something they are useful for (0.5 point
for 1 from each method)
What are glial cells? Name the four types of glial cells and describe a function for each one -
CORRECT ANSWER✔✔- Glial cells assist neuronal activity by providing raw materials,
chemical signals, and structure. The four types of glial cells mentioned in class and the book
are Oligodendrocytes - which myelinate the CNS neurons, Schwann Cells which myelinate
the PNS, Astrocytes that control the local blood flow to increase the amount of blood
reaching more-active brain regions, and microglial cells, primary job is to contain and clean
up debris.
4 Points - One point for each glial cell correct.
