Which of the following structures is responsible for the production of cerebrospinal

Which of the following structures is responsible for the production of cerebrospinal fluid (CSF) in the central nervous system?

A. Dura mater

B. Arachnoid villi

C. Choroid plexus

D. Pia mater

Answer: C

Explanation: The choroid plexus, located in the ventricles of the brain (e.g., lateral ventricles, third ventricle), is composed of specialized ependymal cells and capillaries. It filters blood plasma and secretes CSF, which acts as a cushion for the brain and spinal cord. Arachnoid villi absorb CSF (B is incorrect), while dura mater and pia mater are meninges that protect the CNS (A, D are incorrect).
