(1) Moving inwards from the skull towards the brain, or from the vertebral canal towards the spinal cord, the three meninges are: dura mater or pachymeninx (Greek pachy, meaning thick), arachnoid mater, and pia mater.(2) Coxsackie viruses can also cause meningitis, an infection of the meninges (the three membranes that envelop the brain and spinal cord), and rarely, encephalitis, a brain infection.(3) In infants and children, the most common reason for doing a lumbar puncture is to look for an infection of the meninges , the membrane covering the brain and spinal cord.(4) If the infection spreads to the meninges (the membranes that cover the brain and spinal cord) meningitis can develop.(5) Meningitis is an inflammation of the meninges , the membranes that cover the brain and spinal cord.(6) Epidural hemorrhage presents acutely or subacutely, and usually occurs secondary to the tearing of a middle meningeal artery.(7) Triptans work by vasoconstricting the meningeal blood vessels.(8) The spinal cord is a long shaft of tissue made up of neurons and supporting cells that is covered by meningeal membranes.(9) The innermost meningeal layer, the pia mater, is closely applied to the surface of the brain tissue and carries many small arteries and veins.(10) Pigmented primary intracranial tumors other than meningeal melanocytomas and melanomas are rare.
