Hood: of the maxilla is the galena; q.v.: in Tingitidae the elevated portion of the prothorax, often covering the head.
Opposite the second molar tooth of the maxilla is a papilla, on the summit of which is the aperture of the parotid duct.
About 1 cm. in front of the hamulus and 1 cm. medial to the last molar tooth of the maxilla is the greater palatine foramen through which the descending palatine vessels and the anterior palatine nerve emerge.
Bienvenu said Lowery's injuries included a fractured bone in his upper jaw, called the maxilla, along with fractured teeth and a concussion.

In one fluid motion, her maxilla gathered in the severed head and guided it into her labium.
Oh, and I read "An Enigmatic New Lambeosaurine Hadrosaur (Reptilia: Dinosauria) from the Upper Shale Member of the Campanian Aguja Formation of Trans-Pecos Texas," a weird beast named Angulomastacator daviesi, known thus far only from its boomerang-shaped maxilla bone.
"The operation was carried out by a multidisciplinary team led by Dr Joan Pere Barret, performing the transplant of the entire facial skin and muscles, nose, lips, maxilla, palate, all teeth, cheekbones, and the mandible by means of plastic surgery and micro-neurovascular reconstructive surgery techniques."
