![]() ![]() The skull features numerous foramina through which pass the cranial nerves, the spinal cord, arteries, and veins. Unlike conventional thickness calculation approaches (Beam Propagation, Hildebrand), a novel heat transfer-based approach was developed. ![]() It is composed of two cortical tables the inner and outer tables, and the diploe or marrow space between them (Fig. In this study, the skull bone thicknesses of 150 patients ranging in age from 0 to 72 years were calculated using a novel approach (thermal analysis), and thickness changes were analyzed. The temporomandibular joint connects the lower jaw to the temporal bone and enables movement for speech and mastication. The skull vault is formed by the frontal, parietal, temporal and occipital bones and parts of the zygoma and sphenoid bone. The viscerocranium consists of the unpaired mandible and vomer and the paired zygomatic bones, inferior nasal conchae, lacrimal bones, nasal bones, maxillary bones, and palatine bones. The fontanelles, which comprise the anterior, posterior, and the paired mastoid and sphenoid fontanelles, close between the age of 2 months and 18 months. The bones of the infant neurocranium are not fused but are instead connected by membranous gaps between the bone plates called fontanelles, which enable flexion of the skull to facilitate passage through the birth canal and accommodate the rapidly growing brain. The cranial bones are connected by fibrous joints called sutures. ![]() The neurocranium consists of the frontal, the ethmoid, the sphenoid, the occipital, and the paired temporal and parietal bones. The human skull consists of approximately 30 bones, which can be anatomically divided into the cranial bones ( neurocranium) and the facial bones ( viscerocranium). ![]()
