Notes
The Spatium subarachnoideum is the space deep to the outer layer of of the leptomeninx and containing the arachnoid trabeculae. The spatium is bounded internally by the outer layer of the pia mater, however, and the most appropriate designation is therefore Spatium leptomeningeum (Leptomeningeal space).
