The areas in which the subarachnoid and pia maters are widely separated from each other leading to the widening of the subarachnoid space.
Some of the examples are cisterna magna, pontine cistern, chiasmatic cistern and many others.
subarachnoid space
Subarachnoid hemorrhage is a medical emergency that can result in a sudden, severe headache, nausea, vomiting, and loss of consciousness. It is often caused by a ruptured aneurysm in the brain, which can lead to complications such as stroke, brain damage, and even death if not promptly treated. Early detection and treatment are crucial in improving outcomes for individuals with subarachnoid hemorrhage.
Blood accumulates in the subarachnoid space, which is the area between the arachnoid membrane and the pia mater in the brain and spinal cord. Subarachnoid hemorrhage can occur due to the rupture of a blood vessel in this space, leading to bleeding and accumulation of blood that can cause serious neurological complications.
The subarachnoid space is a space filled with cerebrospinal fluid located between the arachnoid mater and pia mater membranes that surround the brain and spinal cord. It serves as a protective cushion and helps with the circulation of cerebrospinal fluid.
Cerebrospinal fluid is extracted from the subarachnoid space in the brain and spinal cord through a procedure called a lumbar puncture, also known as a spinal tap.
According to lippincott Williams, and Wilkins it is a part of subarachnoid cisterns. It recevies CSF from the 4th ventricle via the lateral aparture of Luschka.
Subarachnoid hemorrhages are classified into two general categories: traumatic and spontaneous.

The Subarachnoid Space between the Arachnoid and Pia layers of the CNS (Central Nervous System)
Subarachnoid hemorrhages are rare, accounting for around 5% of all strokes. They are often caused by the rupture of a blood vessel in the subarachnoid space, which is the area between the brain and the tissues that cover it. While less common than other types of strokes, they are a medical emergency that requires immediate attention.
