The central nervous system

The central nervous system, consisting of the brain and spinal cord, is covered by a special type of connective tissue called the meninges. The meninges has three layers:

• dura mater - this is the outer protective fibrous connective tissue sheath covering the brain and spinal cord

• pia mater — this is the innermost layer which is attached to the surface of organs and is richly supplied with blood vessels to nourish the underlying tissues

• arachnoid mater - this provides a space for the blood vessels and circulation of cerebrospinal fluid.
