Head (craniofacial complex) is a region, where a series of functions are carried out.
	These functions include vision, hearing, speech, mastication, swallowing & digestion, respiration, neural integration, and others.
	The successful execution of a function requires biomechanical protection and support.
	Moss’ craniofacial growth theory: Function of the craniofacial complex region is performed by the Functional Cranial Components (F.C.C).
