GENERAL HISTOLOGY

Detailed explanation-1: -The subdural space is a space between your dura mater and your arachnoid mater. Under normal conditions, this space isn’t a space, but can be opened if there’s trauma to your brain (such as a brain bleed) or other medical condition. The subarachnoid space is a space between your arachnoid mater and pia mater.

Detailed explanation-2: -The subdural space is the space that potentially exists between the meningeal layer of the dura and the arachnoid mater. Similar to the epidural space, the subdural space typically exists only under pathological conditions.

Detailed explanation-3: -The meninges separate three spaces called the epidural space, subarachnoid space, and the subdural space. Each of these spaces contains some important blood vessels, rupture of which can cause headache. The epidural space is a potential space located between the inner surface of the skull and the tightly adherent dura.

Detailed explanation-4: -The subdural space is a potential intracranial space situated between the arachnoid and dura.

Detailed explanation-5: -Three layers of membranes known as meninges protect the brain and spinal cord. The delicate inner layer is the pia mater. The middle layer is the arachnoid, a web-like structure filled with fluid that cushions the brain. The tough outer layer is called the dura mater.
