Question

What is cerebrospinal fluid?

Answer 1

Hint: The brain is a complex organ that is composed of neural tissue as well as some other components like fat. This organ is extremely crucial to the functioning of the rest of the body thus it is shielded by the skull.

Complete answer:
The skull is made up of bone that is quite thick therefore it is the perfect protection for the brain. However, the skull is quite hard and thus it can damage the tissue of the brain which is soft. Thus the cerebrospinal fluid is present around the brain to help solve this issue.
The cerebrospinal fluid is a fluid that is made up of the same components that are found in blood plasma, however, this fluid has no protein content in it and the chemical composition is slightly different. It is produced by the ependymal cells that are found in the brain region. The cerebrospinal fluid surrounds the entire central nervous system.
There are several functions that are carried out by this fluid. It helps to cushion the nerve tissue that is found in the central nervous system. It also helps to get rid of all the waste that is produced by the nervous system and plays a role in the regulation of the substances here.

Note:
The cerebrospinal fluid or CSF is a fluid that is produced by the ependymal cells found in the brain. This fluid surrounds the entire central nervous system which includes the brain and the spinal cord. The CSF helps to protect the brain from impact and it also helps in the regulation of substances.
