subarachnoidalrommet
Subarachnoidalrommet, commonly referred to as the subarachnoid space, is the potential space between the arachnoid mater and the pia mater that surrounds the brain and spinal cord. It contains cerebrospinal fluid and the major cerebral vessels. The space extends from the base of the brain and continues along the spinal cord, forming cisterns such as the subarachnoid cisterns (for example, the cisterna magna and the interpeduncular cistern) and the lumbar cistern.
Cerebrospinal fluid circulates through the ventricular system and flows into the subarachnoid space, entering via openings
The subarachnoid space is clinically significant because disease processes can involve this compartment. Subarachnoid hemorrhage occurs
