An arachnoid mater is a membrane which protects the brain and spinal cord below the dura mater and above the subarachnoid space and the pia mater.
A collection of blood under the dura is a subdural hematoma.Subdural hematomaSubdural hematoma is the medical term meaning accumulation of blood in the space beneath the dura.
epidural space
Epidural is the medical term meaning above the dura mater, or the area between the dur mater and the vertebral body.
The dura mater and the arachnoid are not separated. They are the first two layers of meningeal tissue.
The venous sinuses of the brain lie between the inner and outer layers of the dura mater. They are channels that collect deoxygenated blood from the brain and drain it into the internal jugular veins. These sinuses are situated within the dura mater, specifically in the space known as the "dural venous sinuses," and are not located between the arachnoid mater and pia mater.
The space above the dura mater is called the subdural space. It contains a small amount of fluid that acts as a cushion for the brain. Bleeding or fluid accumulation in this space can lead to subdural hematomas or hygromas.
dura mater- this is the strongest outermost covering and external to it is epidural space filled with adipose and veins arachnoid mater- is a web-like middle cover and deep to it lies the subarachnoid space which is filled with CSF pia mater- is the very thin innermost covering and clings tightly to the brain and spinal cord
Yes, an epidural is administered above the dura mater in the body. It involves the injection of medication into the epidural space, which is the area outside the dura mater. This allows for pain relief by targeting nerves in the spinal canal.
The epidural space separates the dura mater from the bone of the vertebra. This space is filled with fat and blood vessels and is where epidural injections are commonly administered to deliver medication for pain relief. The dura mater is a tough, fibrous membrane that surrounds the brain and spinal cord, providing protection and support.
Between the bony vertebrae and the spinal dura mater.
The meninges are the protective layers of the brain, the dura mater, arachnoid space, and the pus mater
