The cerebrospinal fluid is produced in the lateral ventricles by which structure?

• A. Choroid plexus
• B. Arachnoid granulations
• C. Ependymal lining
• D. Interthalamic adhesion

Answer: (A)

The production of cerebrospinal fluid in the lateral ventricles is carried out by the choroid plexus. This vascular network, covered by ependymal cells, filters plasma and actively secretes CSF into the ventricles. Arachnoid granulations are involved in absorbing CSF into the venous system, not creating it. The ependymal lining lines the ventricles but is not the primary source of CSF production, and the interthalamic adhesion is a thalamic structure without a role in CSF generation.
