GENERAL HISTOLOGY

Detailed explanation-1: -The choroid plexus is a complex network of capillaries lined by specialized cells and has various functions. One of the primary functions is to produce cerebrospinal fluid (CSF) via the ependymal cells that line the ventricles of the brain.

Detailed explanation-2: -The epithelial cells of the choroid plexus secrete cerebrospinal fluid (CSF), by a process that involves the movement of Na(+), Cl(-) and HCO(3)(-) from the blood to the ventricles of the brain. This creates the osmotic gradient, which drives the secretion of H(2)O.

Detailed explanation-3: -Cerebrospinal fluid (CSF) envelops the brain and fills the central ventricles. This fluid is continuously replenished by net fluid extraction from the vasculature by the secretory action of the choroid plexus epithelium residing in each of the four ventricles.

Detailed explanation-4: -CSF is produced mainly by the choroid plexus epithelium and ependymal cells of the ventricles and flows into interconnecting chambers; namely, the cisterns and the subarachnoid spaces.

Detailed explanation-5: -The CSF is secreted by the choroid plexus, a tissue located in each ventricle in the brain. CSF flows from the lateral ventricles to the third and fourth ventricles, then into the subarachnoid space of the brain and spinal cord via openings (foramena) below the cerebellum.
