The meninges refer to the three layers of protective tissues that surround and encase the brain and spinal cord. These layers, known as the dura mater, arachnoid mater, and pia mater, play a vital role in insulating and safeguarding the delicate nervous system structures.
The outermost layer is called the dura mater, which is a thick, tough, and fibrous membrane that closely adheres to the inner surface of the skull. It serves as a protective barrier against external forces and acts as a shock absorber.
Beneath the dura mater lies the arachnoid mater, a delicate, cobweb-like membrane that is situated in close proximity to the dura mater. This layer contains the arachnoid space, a subarachnoid region filled with cerebrospinal fluid that cushions the brain and spinal cord.
The innermost layer of the meninges is the pia mater, which closely adheres to the surface of the brain or spinal cord. It is highly vascularized and provides nourishment to these vital structures.
The meninges collectively provide physical support, mechanical protection, and nutrient supply to the brain and spinal cord. They also participate in the circulation and reabsorption of cerebrospinal fluid, which helps maintain a stable environment for the central nervous system.
In summary, the meninges are a set of three protective membranes that envelop and safeguard the brain and spinal cord, contributing to their structural integrity and functionality.

The word "meninges" derives from the Greek word "mēninges" (plural form) which means "membranes". This word, in turn, comes from the Greek word "mēninx" (singular form) meaning "membrane" or "parchment". The term was first used in the field of anatomy to refer to the three protective layers of connective tissue that surround and protect the brain and spinal cord.
