The emissary veins connect the extracranial venous system with the intracranial venous sinuses. They connect the veins outside the cranium to the venous sinuses inside the cranium. They drain from the scalp, through the skull, into the larger meningeal veins[citation needed] and dural venous sinuses. They may also connect to diploic veins within the skull.[1]

Anatomical terminology |
Emissary veins have an important role in selective cooling of the head. They also serve as routes where infections are carried into the cranial cavity from the extracranial veins to the intracranial veins.
There are several types of emissary veins including the posterior condyloid, mastoid, occipital and parietal emissary veins.[1]
