Selkäydinnesteen

Selkäydinneste, also known as cerebrospinal fluid (CSF), is a clear, colorless fluid that surrounds the brain and spinal cord. It is produced by specialized cells in the ventricles of the brain called the choroid plexus. Selkäydinneste serves several vital functions for the central nervous system.

One of its primary roles is to act as a shock absorber, cushioning the brain and spinal cord from physical trauma. It also plays a crucial role in providing nutrients to the central nervous system and removing waste products. Furthermore, selkäydinneste helps to maintain a stable environment for the brain by regulating pressure and chemical composition. The fluid circulates through the subarachnoid space, the ventricles, and the central canal of the spinal cord.

The composition of selkäydinneste can provide valuable diagnostic information. Analysis of CSF, a procedure known as lumbar puncture or spinal tap, can help detect and diagnose various neurological conditions, including infections such as meningitis, inflammatory diseases like multiple sclerosis, and certain types of cancer that may affect the central nervous system. Abnormalities in the appearance, cell count, protein levels, or glucose levels of selkäydinneste can indicate underlying health issues. The normal pressure of selkäydinneste is also an important diagnostic parameter.
