Eductional Objective: The external carotid artery gives the branch of the maxillary artery. The maxillary artery gives off the middle meningeal artery that enters the skull through the foramen spinosum and passes deep to the pterion ( The junction of the frontal, parietal, temporal, and sphenoid bones). Injuries at the level of pterion lead to middle meningeal artery laceration causing an epidural hematoma.
