  Kabiraj, thanks for the question.

Emissary veins transmit infection at the speed of that the special thing about them??. enlighten us.

all i know is,Emissary veins establish communication between the sinuses inside the skull and the veins external to it.

Azamine, Cavernous sinus is a dural venous sinus. i don't understand how you got confused.
