Thin delicate inner membrane of the meninges

  • The pia mater is a thin delicate membrane which is attached to the brain outer surface. There is a fluid filled space between the dural surface of arachnoid matter and the pia mater be- cause arachnoid mater doesn’t follow the contours of the brain like the pia mater. 3
Meningitis is a relatively rare infection that affects the delicate membranes -- meninges-- that cover the brain and spinal cord. Expat worker continues to battle against brain fever Meningitis is an acute inflammation of the protective membranes covering the brain and spinal cord, known collectively as the meninges .

The meninges consist of three layers: the dura mater, the arachnoid mater, and the pia mater. The primary function of the meninges and of the cerebrospinal fluid is to protect the central nervous system. Anatomy Pia mater. The pia or pia mater is a very delicate membrane.

The middle element of the meninges is the arachnoid mater, so named because of its spider web -like appearance. It cushions the central nervous system. This thin, transparent membrane is composed of fibrous tissue and, like the pia mater, is covered by flat cells also thought to be impermeable to fluid.
  • The meninges comprise three membranes that, together with the cerebrospinal fluid, enclose and protect the brain and spinal cord (the central nervous system).

  • This is a very thin and delicate layer which intimately follows the surface of the brain and spinal cord. It is highly vascularised tissue and its capillaries are responsible for nourishing the brain. Clinical Aspects of the Meninges.

    The pia mater is the meningeal envelope that firmly adheres to the surface of the brain and spinal cord. It is a very thin membrane composed of fibrous tissue covered on its outer surface by a sheet of flat cells thought to be impermeable to fluid. The pia mater is pierced by blood vessels that travel to the brain and spinal cord.

    The outermost layer of the meninges is the dura mater. It is a tough, leathery meninx that consists of an outer periosteal layer and a deeper meningeal layer, which are fused except in certain areas.

    Pia mater is the delicate innermost layer of the meninges. It is a thin fibrous tissue that is impermeable to the fluid that surrounds the cerebrospinal fluid and provides protection to the other layers of the meninges. It acts like a cushion of the brain.
