Due to use of vacines which cause viral mengitis.
dura mater
Duritis is inflammation of the dura mater.
Epidural is the medical term meaning above the dura mater, or the area between the dur mater and the vertebral body.
Situated under the dura mater, or between the dura mater and the arachnoid membrane.
Dura mater deterioration can be caused by several factors, including aging, chronic inflammation, and certain medical conditions such as meningitis or tumors. Additionally, mechanical trauma or surgical interventions can lead to damage and subsequent deterioration of the dura mater. In some cases, vascular issues, like reduced blood flow, may also contribute to its degradation.
The dura mater was so-named because of its tough, fibrous consistency. The pia mater is thinner and more delicate than the dura mater, and is in direct contact with the neural tissue of the brain and spinal cord
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 dura mater belong to the craniosacral system.
The dura mater, the pia mater, and the arachnoid.
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.
The pia mater.There are 3 layers of meninges: the pia mater adheres to the brain and spinal cord; the dura mater is next to the skull, and the arachnoid mater is in-between the two.
No, cerebrospinal fluid (CSF) is not found between the pia mater and dura mater. Instead, CSF is located in the subarachnoid space, which is situated between the pia mater and the arachnoid mater. The dura mater is the outermost layer and is separated from the arachnoid mater by a space called the subdural space, which does not contain CSF.
