Cerebrospinal Fluid (CSF)
Cerebrospinal fluid is a clear, colorless liquid that surrounds the brain and spinal cord, providing cushioning, nutrient delivery, and waste removal. It plays a crucial role in maintaining intracranial pressure and protecting the central nervous system from injury.

Choroid Plexus
The choroid plexus is a network of blood vessels and cells located in the ventricles of the brain that produces cerebrospinal fluid. It filters blood plasma to create CSF, which is essential for the brain's metabolic needs and overall homeostasis.

Arachnoid Granulations
Arachnoid granulations are small protrusions of the arachnoid mater into the dural sinuses that allow for the reabsorption of cerebrospinal fluid into the bloodstream. This process is vital for regulating CSF volume and pressure within the central nervous system.
