Verified step by step guidance
1
Understand the anatomy of the meninges: The meninges are three layers of protective tissue called the dura mater, arachnoid mater, and pia mater that surround the brain and spinal cord.
Identify the location of each meningeal layer: The dura mater is the outermost layer, the arachnoid mater is the middle layer, and the pia mater is the innermost layer.
Define a subdural hematoma: This condition occurs when blood collects between the dura mater and the arachnoid membrane, often due to a head injury that causes tearing of the veins.
Differentiate between the types of hemorrhages: An epidural hematoma occurs between the skull and dura mater, a subarachnoid hemorrhage occurs between the arachnoid mater and pia mater, and an intracerebral hemorrhage occurs within the brain tissue itself.
Conclude that the condition where blood collects between the dura mater and arachnoid membrane is a subdural hematoma, based on the anatomical location of the bleeding.
