GENERAL HISTOLOGY

Detailed explanation-1: -CSF occupies the subarachnoid space (between the arachnoid mater and the pia mater) and the ventricular system around and inside the brain and spinal cord. It fills the ventricles of the brain, cisterns, and sulci, as well as the central canal of the spinal cord.

Detailed explanation-2: -The CSF flows over the surface of the brain and down the length of the spinal cord while in the subarachnoid space. It leaves the subarachnoid space through arachnoid villi found along the superior sagittal venous sinus, intracranial venous sinuses, and around the roots of spinal nerves.

Detailed explanation-3: -This fluid is produced by filtering blood at the choroid plexuses in the four ventricles of the brain. It then circulates through the ventricles and into the subarachnoid space, between the pia mater and the arachnoid mater.

Detailed explanation-4: -The subarachnoid space is the cerebrospinal fluid-filled space that exists between the arachnoid and the pia. Within the lateral ventricles of the brain, the choroid plexus produces CSF, which passes into the subarachnoid space via the foramina of Luschka.

Detailed explanation-5: -Circulation of cerebrospinal fluid (CSF) is a clear, colorless liquid that circulates between the ventricular system and the subarachnoid space. In addition to its function as a natural cushion for the brain, CSF provides the circulation of metabolic products, hormones, and neurotransmitters.
