![]() ![]() Teeth are anchored to the jawbones (maxilla and mandible) through roots, forming a part of the overall skull structure. They are composed primarily of dentin and enamel and serve important functions in biting, chewing, and speech. Teeth are not technically considered part of the skull, but they are vital components of the oral cavity. The mandible, or lower jawbone, is the largest and strongest facial bone, responsible for supporting the lower teeth and facilitating chewing and speaking. The lacrimal bones are the smallest bones in the skull and are located in the inner corners of the eye sockets, playing a role in tear production.

The inferior nasal conchae are delicate bones that project from the lateral walls of the nasal cavity, helping to increase the surface area and improve airflow within the nasal passages. The palatine bones form the posterior part of the hard palate, helping to separate the oral and nasal cavities. The vomer is a small, thin bone that forms the inferior portion of the nasal septum, helping to divide the nasal cavity into left and right sides. The nasal bones form the bridge of the nose, providing support and protection for the nasal passages. The maxilla forms the upper jaw and plays a role in facial structure, holding the upper teeth and providing support to the nasal cavity and eye sockets. The zygomatic bones, commonly known as the cheekbones, form the prominence of the cheeks and contribute to the structure of the eye sockets. The ethmoid bone is located between the eyes and forms part of the nasal cavity, as well as contributing to the eye sockets and skull base. The sphenoid bone is a complex bone that forms the base of the skull and contributes to the eye sockets and nasal cavity. The occipital bone forms the back of the skull, protecting the cerebellum and the visual center of the brain. The temporal bones house the ears and contain important structures like the middle and inner ear, as well as the temporal lobes of the brain. Then the separate cranial bones fuse together and remain that way throughout adulthood. These bony plates cover the brain and are held together by fibrous material called sutures. The major bones that compose the skull of a newborn include the following: 2 frontal bones. In normal development, the cranial bones remain separate until about age two. Although the skull appears to be 1 large bone, there are actually several major bones that are connected together. The paired parietal bones make up the sides and roof of the skull, protecting the top and sides of the brain. Skull Anatomy The human cranium, which houses and protects the brain, is composed of six major bones: the ethmoid, frontal, occipital, parietal, sphenoid and temporal. The frontal bone forms the forehead and protects the frontal lobes of the brain. The skull bones are connected by fibrous joints that fuse together in adulthood to form a rigid structure. The human skull comprises 22 bones, including eight cranial bones that encase and protect the brain and 14 facial bones that form the structure of the face. The skull is a complex bony structure that protects the brain. ![]()
