Document Summary

Venous drainage is composed of the dural veins, superficial cortical veins, & deep veins. Pathway of the venous drainage: all veins to dural sinuses to internal jugular vein. Formed by the great cerebral vein & inferior sagittal sinus. Along the junction of the falx cerebri & the tentorium cerebelli. Occipital sinuses will run there as well. Runs the entire length of the falx cerebri, in the longitudinal fissure. Begins at the crista galli, runs the length of the falx cerebri, & ends at the internal occipital protuberance of the occipital bone. Converges with the great cerebral vein to form the straight sinus. Runs from confluence to the attachment of the tentorium cerebelli to the bone. Within the groove of the occipital bone. As the transverse sinuses passes through the tentorium cerebelli, they merge into the sigmoid sinuses. From the tentorium through the posterior fossa to join with the internal jugular veins. The sigmoid sinuses join the internal jugular veins.
