Dural venous sinuses anatomy ppt

Dural venous sinuses anatomy ppt-Dural venous sinuses are venous channels located intracranially between the two layers of the 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 noteFunctional anatomy • The dural sinuses are designed to maintain the patency in the face of negative pressure • Their triangular shape make them relatively non compressible • Bridging vein entering the sinuses opposite the direction of sinus blood flow • There are no valves • Their wall contain noradrenergic & peptidergic fibres Cerebral venous system physiology Role in
