Cerebrospinal Fluid is produced by the choroid plexus at a rate of 500 ml/day. Its normal pressure is 80 to 180 mm of water (CSF) in the lumbar subarachnoid space when the patient is in a lateral recumbent (decubitus) position. It functions to cushion and protect the central nervous system from trauma and provides mechanical buoyancy and support for the brain. It also serves as a reservoir and assists in the regulation of the contents of the skull, as well as nourishes the central nervous system. The fluid volume is typically 140 ml and its composition contains no more than 5 lymphocytes/µl and usually is sterile. The normal values for this fluid are: 1.pH: 7.35 2.Specific gravity: 1.007 3.Glucose: 66% of plasma glucose 4.Total protein: 45 mg/dl in the lumbar cistern. Cerebrospinal Fluid Circulation flows from the ventricles via the three foramina of the fourth ventricle into the subarachnoid space and over the convexity of the hemisphere to the superior sagittal sinus, where it enters the venous circulation. The Cerebrospinal Fluid transports hormones and hormone-releasing factors and removes metabolic waste products through absorption; the sites of greatest absorption are the ____________.
