  1. Cranium

  2. frontal bone (1) parietal bone (2) occipital bone (1) ethmoid bone (1) sphenoid bone (1) temporal (2) cerebral cranium(8) facial cranium(15) nasal bones (2), lacrimal bones (2), inferior nasal conchae (2) vomer (1), palatine bones (2), hyoid(1) maxillae (2), mandible(1), zygomatic bones(2)

  3. cribriform: cribriform foramina perpendicular plate ethmoidal labyrinth: ethmoidal cellules ethmoid bone squamous part: zygomatic process, articular tubercle , mandibular fossa tympantic part : external acoustic meatus, styloid process , mastoid process petrous part: internal acoustic pore temporal bones
