Final answer:
Option 2). A Subdural hematoma is the collection of blood within the layers of the meninges. The arachnoid mater is the meningeal layer that supports the sinuses for blood drainage from the CNS. A stroke is caused by a disruption of blood flow to the brain.
Step-by-step explanation:
A subdural hematoma is an accumulation of blood inside the meningeal layers. The dura mater, arachnoid mater, and pia mater are the three layers that make up the meninges. Blood exits the Central Nervous System (CNS) through the sinuses, which are surrounded and supported by the arachnoid mater, the middle layer. To be more precise, the arachnoid granulations that emerge into the dural sinuses are where the cerebrospinal fluid (CSF) is reabsorbed into the bloodstream. Blood drainage from the superior aspect of the cerebrum depends on the major veins, such as the superior sagittal sinus, which is situated midsagittally between the meningeal and periosteal layers of the dura mater within the falx cerebri. It is not a meningeal problem that causes a stroke; rather, it is an interruption of blood flow to the brain.
