The meninges consist of three layers: the dura mater, the arachnoid mater, and the pia mater, which is the closest to the cortex. The primary function of the meninges and of the cerebrospinal fluid is to protect the central nervous system.

What are the meninges of the human body?
the three layers of meninges are as follows: Outer layer(layer closet to the skull): known as the Dura Mater. Middle layer: known as the Arachnoid Inner layer(layer closest to the cerebral cortex): known as the Pia Mater ***The meninges contain cerebral spinal fluid (which is produced in the brain stem) which as a shock absorber. The meninges also provide extra support and protection for the brain.controls involuntary muscle
What meninges are affected by meningitis?

Why did meningitis get its name?
Fairly simple one - meningitis is an inflammation (-itis) of the meninges, a set of three membranes which cover the surface of the brain and spinal cord. This leads to a build up of pressure in the head and spine which gives the characteristic headaches associated with meningitis.
What is the function of the layers of the meninges?
-Protect the central nervous system -Responsible for nourshing the brain -Provides cushioning effect for the CNS -Support the large venous channels carrying blood from the brain toward the heart
What are the three connective tissue membranes covering and protecting CNS structure collectively known as?
Beneath the skull are three layers of covering known collectively as the meninges. From the outside in, they are: the dura mater, the arachnoid and the pia mater.
What is the cobweb like structure in the middle meningeal layer?
Spiderweb-like (hence the name) arachnoid layer is one of the three meninges, the membranes that cover the brain and spinal cord. It is interposed between the two other meninges, the more superficial dura mater and the deeper pia mater, and is separated from the pia mater by the subarachnoid space.Arachnoid mater
What are meninges and what are they used for?
Meninges (singular is meninx) is the collective term for the three membranes covering the brain and spinal cord. The meninges are composed of the dura mater (outer), the arachnoid (middle), and the pia mater (inner). In common usage, the membranes are often referred to as simply the dura, pia, and arachnoid.

Is Meningitis is the most accurate term for inflammation of the brain?
Meningitis is inflammation of the meninges, three membranes that are layered around the brain and spinal cord to cushion, nurture and protect the delicate neurons. In order, from superficial to deep, they are the dura mater, arachnoid mater and pia mater. Inflammation of the neurons of the brain would be called encephalitis. Inflammation of the meninges and inflammation of the neurons of the brain are often concurrent; this would be called meningoencephalitis.
What is outermost layer of meninges?
dura materThe dura mater , or pachymeninx, is the tough and inflexible outermost of the three layers of the meninges surrounding the brain and spinal cord....
