Middle meningeal artery
Middle meningeal artery is the largest meningeal branch that arises from the first part of maxillary artery in the infratemporal fossa. It courses through the foramen spinosum to enter the cranial cavity. It gives off numerous branches that supply the dura mater and the bones of the skull. It is the most important of all the dural arteries, supplying two-thirds of the cranial dura with blood. Rupture of this artery can lead to epidural hematoma, not subdural hematoma.

A 46-year-old woman was cut on the right side of her face by a window that shattered. Her laceration was located at the anterior border of the inferior part of the masseter muscle. When she returns to her doctor to have the stitches removed, her physician notes asymmetry in her lower lip when she grimaces as seen in the figure. Damage to what nerve would cause the facial asymmetry seen in this patient?
