Cerebrospinal Fluid

Practice flashcards based on key concepts related to cerebrospinal fluid, its formation, physiology, and handling.

Cerebrospinal Fluid (CSF)

Fluid produced in the choroid plexus, cushioning the brain and spinal cord.

Choroid Plexus

A structure in the brain's ventricles where cerebrospinal fluid is produced.

Subarachnoid Space

The area through which cerebrospinal fluid circulates, providing mechanical protection and homeostasis.

Arachnoid Villi

Protrusions of the arachnoid membrane that allow for the reabsorption of cerebrospinal fluid.

Blood-Brain Barrier (BBB)

A selective barrier that regulates the entry of substances into the cerebrospinal fluid, affecting its chemical composition.

Lumbar Puncture

A procedure for collecting cerebrospinal fluid, critical for diagnosis and requires careful technique.

Specimen Collection

The process of gathering CSF samples into designated tubes for analysis.

Tube Order Importance

The arrangement of tubes for sample collection to minimize contamination and ensure accurate diagnostics.

STAT Handling

Immediate processing of cerebrospinal fluid samples to ensure timely and accurate analysis.

Sample Storage Conditions

Specific requirements for storing CSF samples: refrigerated for hematology, room temperature for microbiology, and frozen for chemistry.
