    Abstract:
    The aim of this work was: 1) differentiation and systematization of the bone elements originated on the base of the nasal septum cartilage, 2) systematization of the cribriform plate, 3) investigation and systematization of the bottom elements of the sphenoid recess in young pairhoofed mammals. The material and methodology was described elsewhere (part I and IV-A). The additional material were 6 skulls of wild boar. The nasal septum diploe constituted of two biomechanical systems: anterior and posterior. The first one is situated in the sphenoid septum and corps. the second in diploe laminae perpendicularis of the alar bone. The cribriform plates and parasphenoid stabilize the osseous nasal septum system in the splanchnocranial space--without signs of the biomechanic binds between diploetic elements. The floor sphenoid recess for two plates: the lamina transversalis posterior and laminae transversalis parasphenoidei. The results of these investigations was the verification of the absence of "mesoethmoid in mammals as well in birds, fishes and amphibians. The traditional system of the ethmoid bone organization in this way turned out to be illusory.
