Explanation Reasons for the correct statement: The choroid plexus region in the brain secretes the cerebrospinal fluid from the ependymal cells. The leakage of the fluid from these capillaries causes the formation of the cerebrospinal fluid. Option (b) is given as “choroid plexus”. As “the site of cerebrospinal fluid production is choroid plexus”, it is the right answer. Hence, option (b) is correct. Reasons for the incorrect statements: Option (a) is given as “dural venous sinus”. It contains the blood vessels supplying blood to the brain...

Chapter 14, Problem 4RQ

Summary Introduction

Introduction:

The choroid plexus region inside the ventricles produces the cerebrospinal fluid (CSF). The ependymal cells are present with microvilli, which secrete the cerebrospinal fluid. There are various tight junctions present in this regions around the cells lining the brain cavity. The fluid leaks out of the blood capillaries to produce the cerebrospinal fluid. The composition of the fluid is different in the blood plasma and the capillaries containing proteins, amino acids, ions, and other metabolites.
