The meninges (from the Greek meninx, meaning "membrane") cover and protect the brain and spinal cord. The meninges have three layers: 1) the dura mater, 2) the arachnoid, and 3) the pia mater. The dura mater is the outermost layer covering the central nervous system. The arachnoid (from the Greek arachne, meaning "spider") is a web-like network of collagen and elastic fibers. The innermost layer of the meninges is the pia mater. The pia mater is firmly attached to the neural tissue of the spinal cord and brain. Cerebrospinal fluid fills the space between the pia matter and the arachnoid membrane. Most of the blood vessels that supply blood to the central nervous system are in the pia mater.

∙ 9y agoThe spinal cord is protected by three layers of tissue called spinal meninges. The outer layer, called the dura matter, forms a tough protective coating. The middle layer, called the epidural space, is filled with adipose tissue and a network of blood vessels. The inner layer, arachnoid mater, has a spider-web like appearance.

Thin innermost membrane attached to surface of the spinal cord?
The thin like membrane that covers the brain is "Dura Matter", and the thin like protection surrounding the spinal cord is a "mylein Sheath".
What does intrathecal mean?
Introduced into or occurring in the space under the arachnoid membrane which covers the brain and spinal cord.
What portions of the body does the dura membrane cover?
The dura membrane covers and protects the brain and spinal cord. It is the outermost layer of the meninges, a system of membranes that surrounds and supports the central nervous system.
Which is the outermost membrane of 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.
What is meningomalacia?
Protrusion of spinal cord membranes through defect in the spinal column.
What is ventral subarachnoid?
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.
How is baclofen used?
Baclofen (Lioresal) may be administered orally or intrathecally (introduced into the space under the arachnoid membrane that covers the brain and spinal cord) for control of spasticity due to neuromuscular disease.
What are the transparent fibrous membrane that forms a tube around the spinal cord?
Pia mater
When the thecal sac is compressed does it affect the pudendal nerve?
The thecal sac is filled with spinal fluid and is located in the membrane of the dura mater near the spinal cord. When the thercal sac is compressed it can affect the spinal column and functions of the spinal cord.
What is the spinal condition where spinal cord grows and tightens the spinal cord?
Tethered Spinal Cord is a condition where the spinal cord is attached to the spinal column and that causes the cord to become stretched.
What are arachnoids?
Anatomy. A delicate membrane that encloses the spinal cord and brain.Zoology. Relating to or resembling spiders.
The tough outer membrane of the spinal cord is called?
Dural sheath or dura matter
