Detailed explanation-1: -Anatomically, the subarachnoid space exists between the arachnoid mater externally and pia mater internally. A network of fine delicate connective tissue called trabeculae connects these two layers and gives this space its characteristic spider web appearance.
Detailed explanation-2: -The spinal subarachnoid space is located between the arachnoid and pia mater and is filled with CSF. Arachnoid trabeculae extend between these two layers within the subarachnoid space to give the subarachnoid space its characteristic spiderweb appearance.
Detailed explanation-3: -The subarachnoid space is the interval between the arachnoid membrane and the pia mater. It is occupied by delicate connective tissue trabeculae and intercommunicating channels containing cerebrospinal fluid (CSF) as well as branches of the arteries and veins of the brain. The cavity is small in the normal brain.
Detailed explanation-4: -When the dura mater and the arachnoid separate through injury or illness, the space between them is the subdural space.
