The meshwork of elastic fibers that give the arachnoid mater a web-like appearance are called arachnoid trabeculae. They are thin, delicate structures that extend across the subarachnoid space, connecting the arachnoid mater to the pia mater. Arachnoid granulations are clusters of villi that project into the dural venous sinuses, while arachnoid extensions are simply protrusions of the arachnoid mater. Subarachnoid spaces are the fluid-filled spaces between the arachnoid mater and the pia mater.
