Question

where does cerebrospinal fluid specifically originate from and what are the three primary functions of csf?

How does the outermost of these tissue layers of the brain differ from that of tge spinal cord?

Answer 1

The cerebro spinal fluid orginates from the arterial blood , by the choroid plexuses of the lateral and fourth ventricles by a combined process of diffusion, pinocytosis and the active transfer. The three primary function of cerebro spinal fluid are ,

• CSF protects brain and the spinal cord from trauma.
• CSF supplies nutrients to the nervous system tissue.
• CSF removes waste products from the cerebral metabolism.

The outer most tissue layer of brain and spinal cord are dura mater. The dura mater is attached to the skull. And in the spinal cord, the dura mater is separated from the vertebrae by a space called the epidural space, which contains fat and blood vessels.
