![]() Vomer – forms the posterior aspect of the nasal septum.Maxilla (2) – comprises part of the upper jaw and hard palate.Palatine (2) – situated at the rear of oral cavity and forms part of the hard palate.Inferior nasal conchae (2) – located within the nasal cavity, these bones increase the surface area of the nasal cavity, thus increasing the amount of inspired air that can come into contact with the cavity walls.Nasal (2) – two slender bones that are located at the bridge of the nose.They form part of the medial wall of the orbit. Lacrimal (2) – the smallest bones of the face.Zygomatic (2) – forms the cheek bones of the face and articulates with the frontal, sphenoid, temporal and maxilla bones.The frontal bone, typically a bone of the calvaria, is sometimes included as part of the facial skeleton. It consists of 14 bones, which fuse to house the orbits of the eyes, the nasal and oral cavities, and the sinuses. Also, the country or place of human beings is a factor that affects the shape of the structure of the human skull.The facial skeleton (also known as the viscerocranium) supports the soft tissues of the face. The largest hole of the skull is called the magnum.Įven in human beings, the skull is different in size and shape depending upon gender, male and female. Space, where the vertebral column and skull base are joined, is the largest hole of the structure of the skull. Holes are for blood vessels and nerves to pass through the face. The skull bone structure has many holes that are called foramina. It includes only the upper jaw, not teeth, and lower jaw. Cranium has eight bones whereas facial bones are fourteen. The bones of the skull are divided into two parts, cranium and face bones. Many mammals, such as the dog, have a sagittal crest down the centre of the skull this provides an extra attachment site for the temporal muscles, which close the jaws. Such as in infants, sutures or space between various skull bones are loose but they change with age. Human beings change the skull structure many times as they grow older. Turbinates bones, lachrymal, nasal, and vomer form the nasal cavity. The facial bones include zygomatic, cheekbones that joints with maxillary and temporal bones that make the zygomatic arch of the eye socket. Temporal and parietal bones form the forehead. The base of the cranial includes ethmoid and sphenoid bones. In humans, the base of the cranium is the occipital bone, which has a central opening (foramen magnum) to admit the spinal cord. Human Skull Diagram: Structure of Human Skull Let’s look at the human skull diagram to know more about the structure of the human skull. The side-to-side motion is possible as the atlas move on the next-lower vertebra called axes. Atlas is the highest vertebra of the human skull that permits nodding motions. The facial structure of the skull is relatively larger than the brain skeleton structure in other animals. The part of the skull that protects the brain is the human cranium and it is globular and large concerning face size. Moreover, the lower jaw is not the part of the human skull but the upper jaw is the part of the human skull. Well, the framework of the human skull consists of cartilage or bones that protect sense organs and the brain too. Openings of the skull are known as fenestrae in zoology.Īs we have discussed earlier in this article, all living beings have different skulls and the human skull diagram includes brain housing and protective structure for sensory organs like eyes, nose, and ears. The skull consists of foramina, processes, and fossae, sinuses or cavities, and various fused flat bones. Some mammals with hooves (horned ungulates animals), skull offers the mount for horns as a defensive structure. Skull fixes the ears position to enable sound localization of distance and direction of sounds. In addition, it also fixes the eye balls’ distance to get proper stereoscopic vision. Well, have you ever thought about how important the skull is? Brain protection is the main function of the skull. Humans have sensory structures like eyes, ears, mouth, nose and all are included in the facial skeleton. ![]() The anterior-most portion of the body is formed by the skull and it is a product of cephalization that includes both housings of sensory structures and the brain. The mandible is the largest bone of the human face structure that is placed in the viscerocranium. In human beings, the skull includes the neurocranium and viscerocranium. All living beings on earth have different kinds of skeleton according to the face and size of the brain. Skull includes two parts, one is the cranium and the other is the mandible. Skull is an English word and it is derived from the old world “skulle”. The structure of the face is supported by the skull. Skull is a bunch of bones that create the head in vertebrates.
