Viscerocranium Bone Complex

Viscerocranium, or the facial skeleton, consists of bones with no cerebral surfaces, i.e., do not contact the intracranial space. The viscerocranium includes six paired (zygomatic, maxillae, palatine, lacrimal bones and the inferior nasal conchae) and two unpaired bones (vomer & mandible).
