Spinal fluid

Spinal Fluid

Spinal fluid, also known as cerebrospinal fluid (CSF), is a clear, colorless body fluid found in the brain and spinal cord. It is produced in the choroid plexus of the brain and serves multiple vital functions in the central nervous system.

Production and Composition

Spinal fluid is produced by the ependymal cells of the choroid plexus at a rate of about 500 mL/day. It is composed of water, glucose, sodium, potassium, calcium, chloride, and magnesium. The fluid also contains small amounts of white blood cells and protein.

Functions

The primary functions of spinal fluid include providing buoyancy and protection to the brain and spinal cord, supplying nutrients, and removing waste products. It also plays a crucial role in maintaining intracranial pressure.

Clinical Significance

Changes in the composition, pressure, or volume of spinal fluid can indicate various medical conditions. These include meningitis, multiple sclerosis, brain tumors, and hydrocephalus. Spinal fluid can be examined through a procedure known as a lumbar puncture or spinal tap.
