The skull is the bony structure that shapes the head and protects the structures of the brain. The bones of its anterior part form the face, while those of the posterior part form the cranial vault.
The bones of the face are distributed forming holes for the eye sockets, nasal cavity and oral cavity.
Distribution of facial bones
We have 14 bones in the face in total:
Malar or Zygomatic Bone . There are two, one on each side, this one gives shape to the cheekbones, constituting an important part of the floor of the eye sockets. From its base, an extension is emitted that goes from behind until it joins the temporal bones. This prolongation is called the zygomatic arch, it is a prominence that can be palpated in front of the ears. Bones of the Face
Proper nose bones . These are two small bones located in the midline below the frontal bone and inside the upper maxillary bone. These bones form the base of the nose and provide an insertion point for the cartilage that forms the nasal septum.
Vomer . It is a single bone, located in the midline, just behind the nose’s cartilage. Its function is to divide the nasal cavity into two channels that correspond to the nasal cavities.
Lacrimal Bone . It is also known as unguis. These are two small bones located on the inner side of the orbit. These bones form the tear duct.
Upper jaw . There are two bones, one on each side, located inside the malar bone, forming the inner wall of the orbit and the roof of the oral cavity. They contain orifices called alveoli, into which the teeth and molars of the upper dental arch are inserted. Bones of the Face
Palatine . They are two bones located at the back of the upper jaw, distributed deep in the midline. These bones form the walls of the nose and have prominences that form the upper and middle nasal turbinates. Its name is due to the fact that it forms the posterior part of the roof of the oral cavity, which corresponds to what is known as hard taste.
Inferior Cornets . These are two bones located below the palatine, giving rise to a curved shell-shaped structure known as the inferior turbinate of the nose. Together with the palatine, they form the outer wall of the nasal cavity.
Lower jaw . Also known as the mandible. It is a bone that forms the lower part of the face. It is attached to the temporal bone, giving rise to the temporomandibular joint, which is the only mobile joint in the head, necessary for speaking and chewing. Like the upper jaw, the mandible consists of a series of orifices called alveoli, into which the teeth and molars of the lower dental arch are inserted. Bones of the Face
