Dural venous sinuses

Dural venous sinuses are venous channels located intracranially between the two layers of dura mater (endosteal layer and meningeal layer). They can be conceptualised as trapped epidural veins. Unlike other veins in the body they run alone, not parallel to arteries. Furthermore, they are valveless, allowing for bidirectional blood flow in intracranial veins. It is also important to note that the draining territories of intracranial veins are different from those of major cerebral arteries. 

Together the dural venous sinuses form the major drainage pathways from the brain, predominantly to the internal jugular veins.

The main dural venous sinuses are:
