Clear fluid occupying the space around and inside the brain and spinal cord.
Clear fluid that bathes the ventricles of the brain and the central cavity of the spinal cord.
The fluid contained within the brain and the subarachnoid space about the brain and spinal cord.
Normally clear liquid, produced in the ventricles of the brain, that fills and protects the cavities in the brain and spinal cord. In the adult there is normally about 140 milliliters of cerebrospinal fluid. Samples of the fluid, obtained by lumbar puncture, may be used to diagnose certain diseases.
A fluid secreted by the choroid plexuses of the ventricles of the brain, filling ventricles, subarachnoid spaces, and the spinal cord.
The fluid that bathes the brain and spinal canal. It may be examined for the presence of blood, infection, and other abnormalities.
Also known as CSF, the clear, watery fluid that circulates inside and around the brain and spinal cord. In a diagnostic test called a lumbar puncture, a sample of CSF is removed for analysis in order to diagnose problems such as bacterial or viral meningitis, inflammation, tumors, hemorrhages, brain abscesses, and neurosyphilis.
The clear watery fluid that surrounds the brain and spinal cord. It is contained in the ‘subarachnoid space and circulates in the ventricles of the brain and in the central canal of the spinal cord. The brain floats in the fluid (its weight so being reduced from about 14(X) g to less than 1(X) g) and is cushioned by it from contact with the skull when the head is moved vigorously. The CSF is secreted by the ‘choroid plexuses in the ventricles, circulates through them to reach the subarachnoid space, and is eventually absorbed into the bloodstream through the arachnoid villi. Its normal contents are glucose, salts, enzymes, and a few white cells, but no red blood cells.
The fluid within the ventricles of the brain, bathing its surface and that of the spinal cord. Normally a clear, colourless fluid, its pressure when an individual is lying on one side is 50 to 150 mm water. A lumbar puncture should not be done if the intracranial pressure is raised.
The sodium-rich, potassium-poor tissue fluid of the brain and spinal cord, which supplies nutrients and removes waste products; it is also a watery cushion that absorbs mechanical shock to the central nervous system.
A watery, colorless, clear fluid that bathes and protects the brain and spinal cord. The composition of this fluid can be altered by a variety of diseases. Certain changes in CSF that are characteristic of MS can be detected with a lumbar puncture (spinal tap), a test sometimes used to help make the MS diagnosis.
A liquid located between the middle and inner meninges and in certain spaces within the brain that helps to cushion and protect the brain and spinal cord.
Fluid that provides nutrients and support to the brain and spinal cord.
Cerebrospinal fluid (CSF) is a vital substance generated within the brain to facilitate the transportation of nutrients and support the brain’s structural integrity. This remarkable fluid circulates through the intricate network of ventricles, which are open spaces nestled within the brain, and subsequently drains through the protective membranes encompassing the brain.
A transparent and watery fluid circulates throughout the ventricles (cavities) within the brain, the central canal in the spinal cord, and the space between the brain and spinal cord, as well as their protective coverings known as the meninges. This fluid, called cerebrospinal fluid, serves as a cushion, playing a vital role in preventing or minimizing damage to the brain and spinal cord following an impact to the head or back. It comprises glucose, proteins, salts, and white blood cells.
Analysis of this fluid, typically obtained through a procedure called lumbar puncture, plays a crucial role in diagnosing various conditions that impact the brain and spinal cord, such as meningitis and subarachnoid hemorrhage. The examination of cerebrospinal fluid samples aids in the identification and assessment of these medical conditions.
The buildup of cerebrospinal fluid inside the skull during fetal development or infancy can lead to the enlargement of the skull, a condition referred to as hydrocephalus. This accumulation of fluid has the potential to cause abnormal growth of the skull.
The clear, colorless fluid found between the arachnoid and pia mater membranes in the brain is known as cerebrospinal fluid. Produced by the choroid plexuses within the brain’s ventricles, this fluid acts as a protective cushion for the central nervous system and facilitates the transfer of nutrients. Its composition can change in response to certain brain diseases, making it a crucial diagnostic tool when collected through a lumbar puncture. This procedure not only measures the fluid’s pressure but can also detect the presence of pathogens and other chemical changes, aiding in the accurate diagnosis of brain diseases or injuries.
