A blood vessel ruptures and bleeds between the meningeal dura mater and arachnoid mater. Which of the following describes the location of this bleed?

Multiple Choice

Dural venous sinus

Subdural space

Epidural space

Subarachnoid space

The correct answer is Subarachnoid space.

Explanation:

The cranial meninges are the layers responsible for enveloping the brain and spinal cord. These layers are: dura mater, arachnoid mater, and pia mater.

Based on these layers there are also three cavities: epidural, subdural and subarachnoid.

The subarachnoid cavity it is located between the arachnoid and the pia, and there we find cerebrospinal fluid that exists between the arachnoid and the pia. This is also where the Cerebrospinal fluid continuously flows as well as the main arteries of the brain pass through this space.

When it is crossed by the main arteries, if a blood vessel breaks and bleeds between the hard meningeal mother and the arachnoid, the location of this bleeding would be in Subarachnoid space.
