Which structure is primarily responsible for the production of CSF?

CSF production is primarily carried out by the choroid plexus, a vascular network lined by ependymal cells within the ventricles. This structure actively secretes CSF from plasma and helps regulate its composition, making it the main source of CSF across the ventricular system. The thalamus, hypothalamus, and pineal gland have roles in sensory relay, autonomic/endocrine functions, and melatonin production, but they do not generate CSF. After production, CSF circulates from the lateral ventricles through the foramen of Monro into the third ventricle, down the cerebral aqueduct to the fourth ventricle, and into the subarachnoid space where it is reabsorbed via arachnoid granulations into the venous system.
