Cerebrospinal fluid is the liquid around your brain and spinal cord. If a doctor thinks you have an illness that affects your nervous system, she might take a sample for testing . Formed primarily in the ventricles of the brain, the cerebrospinal fluid supports the brain and provides lubrication between surrounding bones and the brain and spinal cord. When an individual suffers a head injury, the fluid acts as a. The cerebrospinal fluid (CSF) is produced from arterial blood by the choroid plexuses of the lateral and fourth ventricles by a combined process of diffusion, pinocytosis and active transfer. A small amount is also produced by ependymal cells.The CSF cushions the brain and serves also as a sink that receives products generated by brain catabolism and synaptic function Cerebrospinal fluid definition is - a colorless liquid that is comparable to serum, is secreted from the blood into the lateral ventricles of the brain, and serves chiefly to maintain uniform pressure within the brain and spinal cord cerebrospinal fluid the fluid within the subarachnoid space, the central canal of the spinal cord, and the four ventricles of the brain. The fluid is formed continuously by the choroid plexus in the ventricles, and, so that there will not be an abnormal increase in amount and pressure, it is reabsorbed into the blood by the arachnoid villi at approximately the same rate at which it is produced
Cerebrospinal fluid (CSF) leak occurs when there is a tear or hole in the membranes surrounding the brain or spinal cord, allowing the clear fluid that surrounds and cushions those organs to escape. Many CSF leaks heal on their own, but others require surgical repair Brain Fluid Leak? Answering Your Questions about CSF Leak - Duration: 5:34. McGovern Medical School 9,189 views. 5:34. Anatomy of the Spinal Cord and How it Works - Duration: 3:29 Cerebrospinal fluid removal occurs via bulk flow, and solutes are generally cleared from CSF with the same rate constant regardless of size. Exceptions to this rule include certain neuropeptides and neurotransmitters, for which high-affinity receptors or enzymatic clearance mechanisms are present on the surface of the brain Cerebrospinal fluid flow.

Mechanisms of Cerebrospinal Fluid Formation by Choroid Plexus. Penetration of ions and water into the CNS occurs predominantly across the choroid plexus. 2 Control of brain fluid balance therefore starts with a thorough knowledge of choroidal transport mechanisms. Fluid secretion into the ventricles is mediated by an array of ion transporters asymmetrically positioned at the blood- and CSF. The brain and spinal cord is surrounded by a special fluid called the cerebrospinal fluid, or CSF. The CSF has several different functions. One function is buoyancy, which reduces the net weight of the brain: the weight drops from 1,400 gm without cerebrospinal fluid to about 50 gm with this fluid, according to the University of Washington
