The Bony Framework of the God-Like Mask 



To review at this point the history of the bony 

 framework of the face, we note that the human 

 skull as a whole is a complex consisting of a chon- 

 drocranium, or inner skull, which is preformed in 

 cartilage, and an outer shell of dermal bones, 

 formed in membrane. The chondrocranium com- 

 prises the base of the skull, the sphenoid bone and 

 the olfactory and otic capsules. The outer, or 

 dermocranium, comprises: (a) the roofing bones 

 (nasals, frontals, parietals, and the membranous 

 part of the supraoccipital) ; (b) the orbital elements 

 (lacrymal, jugal, or malar) ; (c) the squamous part 

 of the temporal bone; (e) the maxillary elements 

 (upper and lower jaw bones) ; (f) the palatal bone 

 and the internal pterygoid plate of the sphenoid; 

 (g) the vomer.
