What is "posterior meningeal artery"

n. branch of the ascending pharyngeal artery that supplies the dura mater of the posterior cranial fossa

The posterior meningeal artery is the largest vessel supplying the dura region of the posterior fossa. It typically arises from the ascending pharyngeal artery although other origins have been seen, such as the occipital artery. The artery or its branches enter the cranium through jugular foramen, foramen magnum or hypoglossal canal.
