The human brain is well protected by the skull. Inside the skull, the brain is covered by cranial meninges consisting of an outer layer called dura mater, a very thin middle layer called arachnoid mater and an inner layer (which is in contact with the brain tissue) called pia mater. Pia mater, often referred to as simply thepia, is the delicate innermost layer of the meninges and contours the folds and crevices of the brain.
