![]() In fact, there are twenty three in total, some of which are paired: Ethmoid bone Frontal bone Inferior nasal concha (e) Lacrimal bone (s) Mandible Maxillary bone (s) Nasal bone (s) Occipital bone Palatine bones (s) Parietal bone (s. The skull features numerous foramina through which pass the cranial nerves, the spinal cord, arteries, and veins. Main bones of the skull As you can see from the above skull diagram, there are quite a lot of skull bones. The facial skeleton, as its name suggests, makes up the face of the skull. These include the bones of the skull, spine (vertebrae), ribs. The adult human skeleton is made up of 206 bones. The skull anatomy includes several individual bones that fit. Bones provide the structure for our bodies. The temporomandibular joint connects the lower jaw to the temporal bone and enables movement for speech and mastication. The mandible is the largest bone of the fascial skeleton (viscerocranium).Besides the bones of the middle ear, the mandible is the only mobile bone in the skull. The cranial bones compose the top and back of the skull and enclose the brain. The human skull is composed of the bones and cartilage that surround the brain and make up the upper part of the head. 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). At the simplest level, the skeleton is the framework that provides structure to the rest of the body and facilitates movement. ![]()
