The cisterna is a specialized cavity or space within the body, particularly within the brain or spinal cord. It refers to a reservoir or collection of cerebrospinal fluid (CSF) that serves important functions in supporting and protecting the central nervous system. The cisterna acts as a storage area for CSF, allowing for the continuous production, circulation, and drainage of this fluid. It provides cushioning to the brain and spinal cord, helping to protect them from mechanical shocks and trauma. The cisterna plays a crucial role in maintaining the appropriate pressure and balance of CSF, ensuring optimal functioning of the central nervous system.
