Cerebrospinal fluid (CSF) is a clear, colorless body fluid found within the tissue that surrounds the brain and spinal cord of all vertebrates. CSF is produced by specialized ependymal cells in the choroid plexus of the ventricles of the brain, and absorbed in the arachnoid granulations .
Following is a list of reference ranges for cerebrospinal fluid: Ions and metals. Reference ranges for ions and metals in CSF [1] Substance Lower limit Upper limit
Oligoclonal bands (OCBs) are bands of immunoglobulins that are seen when a patient's blood serum, or cerebrospinal fluid (CSF) is analyzed. They are used in the diagnosis of various neurological and blood diseases. Oligoclonal bands are present in the CSF of more than 95% of patients with clinically definite multiple sclerosis. [1]
The blood–cerebrospinal fluid barrier (BCSFB) is a fluid–brain barrier that is composed of a pair of membranes that separate blood from CSF at the capillary level and CSF from brain tissue. [14] The blood–CSF boundary at the choroid plexus is a membrane composed of epithelial cells and tight junctions that link them. [ 14 ]
The granulations are thought to mediate the draining of cerebrospinal fluid (CSF) from the subarachnoid space into the venous system. [ 1 ] The largest and most numerous granulations lie along the superior sagittal sinus ; they are however present along other dural sinuses as well.
Lymphocytic pleocytosis is an abnormal increase in the amount of lymphocytes in the cerebrospinal fluid (CSF). It is usually considered to be a sign of infection or inflammation within the nervous system , and is encountered in a number of neurological diseases , such as pseudomigraine, Susac's syndrome, and encephalitis.
Discovery and description of cerebrospinal fluid [ edit ] Although the first known observations of the CSF date back to Hippocrates (460–375 BCE) and later, to Galen (130–200 CE), its discovery is credited to Emanuel Swedenborg (1688–1772 CE), who, being a devoutly religious man, identified the CSF during his search for the seat of the ...
Intracranial pressure (ICP) is the pressure exerted by fluids such as cerebrospinal fluid (CSF) inside the skull and on the brain tissue. ICP is measured in millimeters of mercury and at rest, is normally 7–15 mmHg for a supine adult. This equals to 9–20 cmH 2 O, which is a common scale used in lumbar punctures. [1]
