Divisions: a line drawn from the supraorbital ridge to the mastoid process separates the skull into two major parts: 1) neurocranium - houses the brain, including the anatomical. 2) apparatus for hearing and vestibular function. splanchnocranium splanchno means related to. This is the facial region, which houses the receptor organs for other special senses including smell, taste and vision. b. Bones may be classified as paired and unpaired: 1) paired bones include the maxillae, palatines, nasals, inferior conchae, lacrimals, zygomatics, temporals and parietals. unpaired bones include the frontal, ethmoid, mandible, occipital, and sphenoid [ femvos ]. The frontal bone develops as two bones separated by the metopic suture, which seldom persists after birth. Identify selected landmarks and details of the cranial bones. a. Fontanelles (fonticuli) - in fetuses and infants, the bones of the calvarium are separated by fibrous connective tissue at sutures.
