The zygomatic bone also takes part in forming the floor of the orbit, as well as the temporal fossa and the infratemporal fossa. The lacrimal bone is very small and quite delicate. The cheekbones have three surfaces, four processes, three foramina, and three articulations. A maxillary bone provides tooth sockets for the superior teeth, forms part of the ORBIT, and contains the MAXILLARY SINUS. Infratemporal fossa6. The upper jaw (maxilla) is the central bone of the midface and thus of the facial portion of the skull (viscerocranium). an upper jaw especially of humans and other mammals in which the bony elements are closely fused.

The Maxillæ (Upper Jaw) - Human Anatomy. A maxillary bone provides tooth sockets for the superior teeth, forms part of the ORBIT, and contains the MAXILLARY SINUS. A notch called the hamular notch distinguishes the maxillary tuberosity of each maxilla from the neighboring pterygoid process of the sphenoid bone. They are considered the keystone bones of the face because they articulate with all other facial bones except the mandible (lower jawbone). The viscerocranium comprises: 1 ethmoid bone; 2 lacrimal bones; 2 nasal bones; 1 vomer; 2 inferior nasal conchae (turbinates) 2 palatal bones The maxilla pertains to the upper jawbone. The maxillae form the upper jawbone and meet each other at a median intermaxillary suture. The maxillae meet in the midline of the face and often are considered as one bone.
