Question

What is the function of cerebrospinal fluid?

Answer 1

Hint: Cerebrospinal fluid is secreted by anterior and posterior choroid plexus and is found inside the ventricles of the brain, central canal of the spinal cord.

Complete Answer:
A) Frontal lobe
B) Cerebellum
C) Spinal cord
The brain is a highly developed organ in human beings.
- It is formed of a very large number of neurons. It is a present in a bony case called cranium, which protects from external injuries. The brain is covered by three meninges i.e. Durometer, Arachnoid Parameter Between the meninges the space is filled with cerebrospinal fluid.
- It protects the brain from shocks and mechanical injury, Cerebrospinal fluids provide protection of the brain and spinal cord – by the shock absorbing medium. It acts as a cushion to Jolts the central nervous system.
- The purpose of the fluid is to protect the brain and spinal cord. It also carries away disposed material.
1) It provides buoyancy to the Brain: The brain weight is about 1400g, but due to the presence of CSF creating a bath, it only has a net weight of 50 g.
2) Homeostasis: Regulates the distribution of metabolites surrounding the brain keeping the environment ideal to present any damage to the nervous system.
3) Cleaning Waste: Waste products produced by the brain more into the CSF which then clears out through the arachnoid granulation into the venous sinus. So it can be absorbed into the bloodstream.
4) Endocrine medium for the brain: Certain hormones are released into CSF. These hormones are carried to different parts of the brain by CSF where they act.

Note: Cerebrospinal fluid (CSF) is a clear, colorless body fluid found in the brain and spinal cord. It is produced by specialized ependymal cells in the choroid plexuses of the ventricles of the brain, and absorbed in the arachnoid granulations.
