dural sinuses, cerebral sinuses, or cranial sinuses
Dural venous sinuses are formed in areas where the two layers of the dura mater separate, forming spaces
Dura mater is composed of dense irregular connective tissue.
The innermost membrane, the pia mater, consists mainly of small blood vessels and is the most vascular of the three meninges.

The dura mater which is Latin for "tough mother" and would also make a kickin' name for a sports team.
The outer layer of the meninges is called as Dura matter. It has got the outer or parietal layer. The inner one is called as visceral layer. This layer is very tough in nature. The outer layer is attached to the skull bones. The inner one get along with the folds of the brain tissue. It creates many partitions in the brain. The gaps between the two gives you the various venous sinuses in the meninges.
A fistula is an abnormal pathway between 2 anatomic spaces or a pathway that leads from an internal cavity or organ to the surface of the body. A sinus tract is an abnormal channel that originates or ends in one opening.
Meningitis is inflammation of the three layers of tissue that surround the brain and spinal cord, collectively called the meninges; separately they are the pia mater, dura mater and subarachnoid mater.

no i do not have venous blood in my brain! at least i dont think so. hope not! well that would explain why i am dead. i hope this helps others! i hope it helps me too!
In conjunction with the other meningeal membranes, pia mater functions to cover and protect the central nervous system (CNS), to protect the blood vessels and enclose the venous sinuses near the CNS, to contain the cerebrospinal fluid (CSF) and to form partitions with the skull. Additionally, it produces some CSF and helps circulation of it. It has been found to have a role as being the brain's "lymphatic system". It helps produce the Blood brain barrier. And pia mater has a huge role in spinal chord deformation under compression.
