What is the dura mater?

Mater, or Pachymeninx, is the farthest, hardest and most fibrous of three membranes or mening, which covers the brain and spinal cord. PIA Mater and Arachnoid mater form the remaining layers of mening, while the PIA mater is the innermost layer. It consists of two layers; A superficial layer and deeper dura mater own.

Meninges is filled with cerebrospinal fluid between PIA Mater and Arachnoid. The primary function of cerebrospinal fluid and meninges is to cover and protect the central nervous system. Be the hardest, the farthest layer, the dura mater, often called only dura, is stronger than the other two layers and helps to reduce the movement of the brain in the skull. Parts of this hard layer also divide the brain into their two hemispheres.

Dura Mater also has several cavities similar to veins that help transfer blood rich in the heart after traveling to the brain. While these veins do not have the diversion of normal blood flow. Excessive bleeding that causes the collection of abnormal amounts of blood limitIt is also called subdural hematoma and arachnoid. This condition is usually the result of a head injury from trauma. Similarly, the collection of blood between the dura and the inner skull is called epidermal hematoma and is usually the result of arterial bleeding.

Dura Mater was used for grafting, especially during neurosurgery, but also in other procedures. It is also known that a disease known as Creutzfeldt-Jakob's disease (CJD), which is a rare, degenerative brain disease, is also broadcast during such graft.

Meningitis is an infection of mening, which is most often caused by a virus, but can also be caused by bacteria. Bacterial meningitis is less common, but is much more serious than viral meningitis, which often solves your own without treatment. Fever, rigid neck and severe headache are common symptoms of meningitis in which two cause the effect of infection on the dura mater and other membraney.
