VEINS OF THE HEAD AND NECK: CSF DYNAMICS AND THE VENOUS SINUSES AND EMISSARY VEINS

There is discussion of the superficial and deep cerebral venous systems, one draining the cerebral hemispheres and the other more constant draining the basal ganglia and thalamus. The formation and tributaries of the internal jugular vein is discussed. Then the basic anatomy of the dural venous sinuses including details of the superior and inferior sagittal, transverse, straight, tentorial, sigmoid, occipital, basilar, superior and inferior petrosal sinuses as well as separate considerations of the design of the cerebral venous drainage. The input and output channels of the cavernous sinus is included. The vertebral venous plexi, emissary veins and the CSF dynamics and anatomy of drainage are considered.
