Regions of the head and face (Latin)

Most of the regions in the neurocranial portion correspond to underlying bones/landmarks of the same name. The exception to this is the regio auricularis, that contains the auris externa/auricula. The regions of the viscerocranium are named according to bony or soft tissue structures of the face. The regio orbitalis contains the organs, bones and soft tissue of the orbita. Inferior to this is the regio infraorbitalis, overlying the maxilla, and the regio zygomatica, named after the os zygomaticum. The regio nasalis contains the bone, cartilage and other tissues of the nasus (nose), while the regio oralis below contains the structures of the cavitas oris. The regio buccalis is named after the latin 'bucca', which refers to the cheek (largely comprised by the m. buccinator), while the regio parotidomasseterica is named after the underlying glandula parotidea and m. masseter. The inferior-most region of the face is the regio mentalis, demarcating the chin (Latin = mentus).
