| Where does most cerebrospinal fluid originate? | View Page |
| Which of the following are functions of CSF? | View Page |
| The image is a stained smear of cerebrospinal fluid. The cell in this slide could be caused by what condition? | View Page |
| Three Main Functions of CSF Cerebrospinal fluid has three main functions:CSF protects brain and spinal cord from trauma.CSF supplies nutrients to nervous system tissue.CSF removes waste products from cerebral metabolism.

| Bloody Specimen When blood is present in a CSF specimen, it is necessary to determine whether the blood is due to a traumatic puncture or to a pathologic condition. There are several clues to help make this distinction:
Traumatic tap:More blood is present in tube 1 than in tubes 2, 3, or 4.When sample is centrifuged within one hour, supernatant is clear.Blood clots on standing.Subarachnoid or cerebral hemorrhage:Blood is evenly distributed in all tubes.When sample is centrifuged within one hour, supernatant is pink or yellow.Blood does not clot on standing. | View Page |
| Xanthochromia Samples from patients who have suffered a subarachnoid hemorrhage or cerebral hemorrhage may have a pink- to yellow-tinged supernatant when the sample is centrifuged within one hour after collection.
The term used to describe the colored supernatant is xanthochromia. The color varies according to the substance causing the color and the length of time after the incident that the sample is examined.

| Cells Several types of cells are present in this slide from a patient who has suffered a cerebral hemorrhage. Lymphs, segmented neutrophils, one monocyte and mature red cells can be easily identified. | View Page |
| CSF lymphocytosis is associated with all of the following except: | View Page |
| Match the name of each dematiaceous fungus listed in the drop-down box with its most likely disease. | View Page |
| Saprophytic Cladosporium species may be difficult to differentiate from Cladosporium trichoides (Xylohypha bantianum) in culture as both produce chains of conidia separated by distinct scars or dysjuncters. Each of the following characteristics of Cladosporium trichoides are helpful in separating the two except: | View Page |
| Match the complications that are most likely to be associated with each of the two yeast diseases that are listed in the drop-down box: | View Page |
| These suspicious forms were recovered in cerebral spinal fluid (CSF). They are responsible for causing: | View Page |
