The myelin sheath forms a protective layer over nerves. However, it is not present on all nerves. Retinal nerves for instance normally are devoid of myelin.
The dura is the tough, fibrous outermost membrane covering the brain and the spinal cord.
The lining of the spinal cord is called the "Dura". It is not Dura, Dura is a meninge which is the top layer of protective covering for both the brain and the spinal cord. The lining of the spinal cord is called the Endyma, it is derived from a Greek word and you can google the variations. PS: The other two meninges are the Arachnoid which is second and a membrane called Pia mater which surrounds the brain.
The most delicate membrane covering the brain is the arachnoid mater. It is a thin, transparent membrane that lies between the dura mater and the pia mater, and is important for protecting the brain and spinal cord.
what is found between the inner and middle membrane s that serves as cushion for the brain
The outermost covering of the brain is called the dura mater. It is a tough membrane composed of dense irregular connective tissue that helps protect the brain and spinal cord. Adhering to the inside surface of the skull, the dura mater also forms partitions that divide the brain into compartments.
membranes that protect the brain and spinal cord
The dura mater is the outermost membrane of the brain and spinal cord. The dura mater is is responsible for keeping in the cerebrospinal fluid.
It is the area between the pia matter and the arachnoid membrane of the brain. The pia matter is part of the membrane that surrounds the brain and spinal cord. The arachnoid membrane is the inner layer of three layers that surround the brain and spinal cord.
The Brain and Spinal Chord comprise the Central Nervous System.
Meningitis is an infection of the fluid that surrounds the spine and brain.
It is an inflammation of the "meninges," or membranes covering the brain and spinal cords.
Myeloneuritis is inflammation of the spinal cord and nerves. Meningitis is inflammation of the membranes covering the brain and spinal cord.
