1What is the purpose of the dura mater?
to maintain position of the brain, keeps everything attached&anchored to the skull
2How does the glucose in CSF relate to plasma glucose?
CSF glucose is 60-70% of plasma glucose
3What is the circulation of CSF?
Able to bring nutrients to cells of nervouse system and waste products go back to blood (to get filtered in the kidneys)
4What is the purpose of ependymal cells?
Filters the blood from the brain and generate spinal fluid and put into ventricles
5What does chemistry test from CSF?
glucose, lactate, protein analysis
6Why shouldn’t the first tube go to microbiology/cell counts?
because it can contain contaminants and blood
7What is the difference between fungal and viral infection?
both: WBC&lymphocytes increase, but
Fungal : % of monocytes increase are much more than viral infection

11What is a defining characteristic of plasma cells under the microscope?
large nucleus pushed to the side, blue-ish basophilic cytoplasm
12What disease do you see plasma cells?
multiple sclerosis
13How can glucose in CSF indicate tumor cells?
tumor cells burn glucose at a higher rate.
Recall: glucose in CSF should be 60-70% of plasma
ex. 100 mg/dL in blood but only 35 mg/dL in CSF
14What makes lactate?
the breakdown of glucose
