"The maxillae (or maxillary bones) are a pair of symmetrical bones joined at the midline, which form the middle third of the face. Each maxilla forms the floor of the nasal cavity and parts of its lateral wall and roof, the roof of the oral cavity, contains the maxillary sinus, and contributes most of the inferior rim and floor of the orbit. It bears the upper tooth-bearing alveolar process."
"The maxilla is sometimes called the upper jaw, usually in relation to the dentition."

"The body of the maxilla is roughly pyramidal and has four surfaces that surround the maxillary sinus, the largest paranasal sinus: anterior, infratemporal (posterior), orbital and nasal. It also has four processes: zygomatic, frontal, alveolar, and palatine. It articulates with the following bones: frontal, ethmoid, nasal, zygomatic, lacrimal, middle nasal concha, inferior nasal concha, palatine, and vomer."
"triangular in shape; forms most of the orbital floor"
"nasolacrimal groove is anterior to the ostium; comprises two-thirds of the nasolacrimal canal circumference"
"horizontal; projects medially from the lowest part of the medial aspect of the maxilla"
"contains two grooves posterolaterally that transmit the greater palatine vessels and nerves; additionally, many vascular foramina and depressions for palatine glands"
"pyramid-shaped projection at which anterior, infratemporal and orbital surfaces converge"
