Cerebrospinal Fluid


Cerebrospinal fluid is a clear, colorless body fluid found in the brain and spinal cord.

The spinal cord is a long, thin, tubular bundle of nervous tissue and support cells that extends from the medulla oblongata in the brainstem to the lumbar region of the vertebral column.

The brain is an organ that serves as the center of the nervous system in all vertebrate and most invertebrate animals.

Body fluid, bodily fluids or biofluids are liquids originating from inside the bodies of living people.

It is produced in the choroid plexuses of the ventricles of the brain.

It acts as a cushion or buffer for the brain, providing basic mechanical and immunological protection to the brain inside the skull.

Immunology is a branch of biology that covers the study of immune systems in all organisms.


The CSF also serves a vital function in cerebral autoregulation of cerebral blood flow.

Cerebral circulation is the movement of blood through the network of cerebral arteries and veins supplying the brain.

Cerebral autoregulation is a process in mammals, which aims to maintain adequate and stable cerebral blood flow.


The CSF occupies the subarachnoid space and the ventricular system around and inside the brain and spinal cord.

In the central nervous system, the subarachnoid space is the anatomic space between the arachnoid mater and the pia mater.

The ventricular system is a set of four interconnected cavities in the brain, where the cerebrospinal fluid is produced.


It constitutes the content of the ventricles, cisterns, and sulci of the brain, as well as the central canal of the spinal cord.

There is also a connection from the subarachnoid space to the bony labyrinth of the inner ear via the perilymphatic duct where the perilymph is continuous with the cerebrospinal fluid.

Perilymph is an extracellular fluid located within the cochlea in two of its three compartments: the scala tympani and scala vestibuli.

In the anatomy of the human ear, the perilymphatic duct is where the perilymphatic space is connected to the subarachnoid space.

The bony labyrinth is the rigid, bony outer wall of the inner ear in the temporal bone.
