facial skeleto viscerocranium, or splanchnocranium � The facial bones are the bones of the anterior and lower skull. �

facial bones include these fourteen bones: � Maxilla (2) � Inferior nasal concha (2) � Lacrimal bones (2) � Mandible � Nasal bones (2) � Palatine bones (2) � Vomer � � Zygomatic bones (2)

facial bones � include these fourteen bones: � Maxilla (2) � Inferior nasal concha (2) � Lacrimal bones (2) � Mandible � Nasal bones (2) � Palatine bones (2) � Vomer � Zygomatic bones (2)

Maxilla � The maxillae are the two maxilla bones forming the upper jaw and palate of the mouth. The two halves are fused at the intermaxillary suture to form the upper jaw.

Each half of the fused maxillae consists of: � The body of the maxilla � � Four processes � � The zygomatic process The frontal process of maxilla The alveolar process The palatine process Infraorbital foramen � The maxillary sinus �

Palatine Bone � is situated at the back part of the nasal cavity between the maxilla and the pterygoid process of the sphenoid bone. � It contributes to the walls of three cavities: the floor and lateral wall of the nasal cavity, the roof of the mouth, and the floor of the orbit

It resembles the letter L & consists of: � a horizontal plate a perpendicular plate � three outstanding processes(the pyramidal process, the orbital and sphenoidal process �
