A collection of blood under the dura is a subdural hematoma.
Subdural hematoma
Subdural hematoma is the medical term meaning accumulation of blood in the space beneath the dura.
Epidural is the medical term meaning above the dura mater, or the area between the dur mater and the vertebral body.
The collection of blood within the meningeal layers refers to a hematoma, which can occur in the space between the meninges—specifically, the dura mater, arachnoid mater, and pia mater—surrounding the brain and spinal cord. There are different types of hematomas, such as epidural and subdural hematomas, depending on their location relative to the dura mater. These collections of blood can result from trauma, such as head injuries, and can lead to increased intracranial pressure and neurological complications if not treated promptly.
I think you mean pia mater which is the innermost layer of the meninges. It is a thin layer that is attached to the brain and spinal cord and has many blood vessels and neurons.
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.
The subarachnoid space, located between the arachnoid mater and pia mater, contains cerebrospinal fluid (CSF). This fluid acts as a cushion for the brain and spinal cord, providing protection and helping to maintain intracranial pressure. Additionally, the subarachnoid space contains blood vessels that supply the central nervous system.
The dura mater forms the dural venous sinuses, which are venous channels located between the layers of the dura mater in the brain. These sinuses are important structures for draining blood and cerebrospinal fluid from the brain.
Between the Arachnoid mater and the Pia mater
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 is located inside the brain. They are sinus like venous channels that drain the blood from the brain, and are divided into two categories being the postero-superior which is located at the upper and back part of the skull and the antero-inferior which is located at the base of the skull.
Mater Hospital is located on Eccles Street in Dublin. Dublin is the capital city of Ireland. Ireland is located near to the United Kingdom and is in Europe.
The subarachnoid space is located between the arachnoid mater and the pia mater, which are two of the layers that surround the brain and spinal cord. It is filled with cerebrospinal fluid, providing cushioning and support to the central nervous system.
