What is another name for cerebrospinal fluid?
Cerebrospinal fluid is made by tissue called the choroid plexus in the ventricles (hollow spaces) in the brain. Also called CSF. Cerebrospinal fluid (CSF, shown in blue) is made by tissue that lines the ventricles (hollow spaces) in the brain.
What are the constituents of cerebrospinal fluid?

| Water content (% wt) | 99 | 93 |
| Protein (mg/dL) | 35 | 7000 |
| Glucose (mg/dL) | 60 | 90 |
| Osmolarity (mOsm/L) | 295 | 295 |
What is the medical definition for cerebrospinal?
Medical Definition of cerebrospinal : of or relating to the brain and spinal cord or to these together with the cranial and spinal nerves that innervate voluntary muscles.
What is cerebrospinal fluid composed of quizlet?
A clear colorless liquid formed in the VENTRICLES of the BRAIN by SECREATION from the CHOROID PLEXUS. CSF IS MADE FROM THE CHOROID PLEXUS AND LINED WITH THE EPENDYMAL CELLS. You just studied 20 terms!
Where is cerebrospinal fluid made?
cerebral ventricles
CSF formation. Most CSF is formed in the cerebral ventricles. Possible sites of origin include the choroid plexus, the ependyma, and the parenchyma[2]. Anatomically, choroid plexus tissue is floating in the cerebrospinal fluid of the lateral, third, and fourth ventricles.
What spaces around the spinal cord is filled with CSF?
The space under the arachnoid, the subarachnoid space, is filled with cerebrospinal fluid and contains blood vessels. The pia mater is the innermost layer of meninges.
How is spinal fluid produced?
CSF is produced mainly by a structure called the choroid plexus in the lateral, third and fourth ventricles. CSF flows from the lateral ventricle to the third ventricle through the interventricular foramen (also called the foramen of Monro).
What is meant by volitional?
1 : an act of making a choice or decision also : a choice or decision made. 2 : the power of choosing or determining.
What is cerebrospinal fluid secreted by?
CSF is secreted by the CPs located within the ventricles of the brain, with the two lateral ventricles being the primary producers. CSF flows throughout the ventricular system unidirectionally in a rostral to caudal manner.
Does cerebrospinal fluid have the same composition as blood plasma?
has almost the same composition as blood plasma.
How is CSF formed and drained?
Blood Supply and Lymphatics The choroid plexus mostly synthesizes CSF. Arachnoid granulations are responsible for CSF resorption; they drain CSF into the dural venous sinuses. CSF drains into the lymphatic circulation, via lymph ducts contiguous to the olfactory duct, as it passes through the cribriform plate.
How does CSF maintain homeostasis?
Chemical stability: CSF flows throughout the inner ventricular system in the brain and is absorbed back into the bloodstream, rinsing the metabolic waste from the central nervous system (CNS) through the blood-brain barrier.
What are the components of cerebrospinal fluid?
Since the cerebrospinal fluid contains nutrient substances such as glucose, proteins, and sodium chloride, and also some waste products such as urea, it is believed to play a role in metabolism. The major constituents of cerebrospinal fluid are water, glucose, sodium chloride, and protein.
Where is the cerebrospinal fluid located in the brain?
pertaining to 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.
What is spinal fluid?
Spinal fluid Neurology A clear, colorless fluid that contains small quantities of glucose and protein, which surrounds the brain, spinal cord, ventricles, subarachnoid space, and the central canal of the spinal cord, provides nutrients, and acts as a shock absorber; CSF analysis is accomplished by lumbar puncture; WBCs or bacteria in the CSF
What is the normal cerebrospinal fluid pressure?
The normal cerebrospinal fluid pressure is 5 mm Hg (100 mm H 2 O) when the individual is lying in a horizontal position on his side.
