Question

Fluid present in and around the central nervous system is

• A. Cerebral fluid
• B. Cerebrospinal fluid
• C. Spinal fluid
• D. Tissue fluid

Answer 1

The correct option is B Cerebrospinal fluid

The central nervous system consists of the brain and the spinal cord. The cavities of the central nervous system are called the ventricles that are lined with the choroid plexus. The choroid plexus is made up of the inserted piamater, blood vessels, the ependymal cells. It is responsible for the formation of the formation of the extracellular fluid called the cerebrospinal fluid which drains the ventricles of the brain and spinal cord. The CSF returns to blood via the arachnoid villi.

Hence, the correct answer is 'Cerebrospinal fluid'
