The brain structure that produces cerebrospinal fluid is the?

• A. Pineal gland
• B. Choroid plexus
• C. Hippocampus
• D. Thalamus

Answer: (B)

Cerebrospinal fluid is produced by the choroid plexus, a network of ependymal cells with capillaries lining the brain’s ventricles. These cells actively secrete CSF, which then fills the ventricular system and flows into the subarachnoid space to cushion the brain, remove waste, and help maintain chemical stability. The choroid plexus is located within the ventricles, especially the lateral, third, and fourth ventricles. The other structures have different roles: the pineal gland secretes melatonin, the hippocampus is key for memory, and the thalamus serves as a major relay center for sensory information.
