Introduction[edit | edit source]
The meninges is a layered unit of membranous connective tissue that covers the brain and spinal cord. They envelope the central nervous system (CNS) structures so that they are not in direct contact with the bones of the spinal column or skull.
- There are three layers from superficial to deep the: dura mater; arachnoid mater; pia mater.
- Each layer of the meninges serves a vital role in maintenance and function of the central nervous system[1].
Function[edit | edit source]
The meninges functions primarily to protect and support the CNS , forming a protective barrier safe guarding the sensitive organs of the CNS against trauma. The meninges
- Deliver blood to CNS tissue via many blood vessels.
- Produces cerebrospinal fluid (CSF), the clear fluid that fills the cavities of the cerebral ventricles and surrounds the brain and spinal cord. CSF protects and nourishes the nervous tissue, acting as a shock absorber, circulating nutrients, and by getting rid of waste products[1].
