Question

question 34
formation of the cerebrospinal fluid occurs in the
ventricles.
meninges.
choroid plexus.
solar plexus.

Explanation:

Cerebrospinal fluid (CSF) is produced by the choroid plexus. The choroid plexus is a network of capillaries and specialized ependymal cells located within the ventricles of the brain. It filters blood plasma to produce CSF. The ventricles are the cavities where CSF circulates, not where it is formed. The meninges are the protective membranes around the brain and spinal cord. The solar plexus is a part of the autonomic nervous system (abdominal region) and has no role in CSF production.

Answer:

choroid plexus.
