Introduction. The dura mater often gets referred to as merely the dura. It is one of the layers of connective tissue that make up the meninges of the brain (pia, arachnoid, and dura, from inside to outside). It is the outermost layer of the three meninges that surround and protect the brain and spinal cord.
