The development of the human embryo in the gastrulation period inside the mother’s body is a very complex process. During the development in the early stages of the embryo different structures and organs are formed. These organs develop throughout the gastrulation process and thus the child is fully developed at the end of the period. Bones are also formed at the same time. These bones fuse to form different structures.
The face of humans is also formed of many bones. These bones are present in fragments in the early stages of development, but later on, the fusión del hueso facetario occurs and the bones fuse to give the perfect shape to the face. But due to some errors while developing there are chances that some bones in the face may not be fused giving rise to some unique features in the face and there are several options for different kinds of surgery to fuse these bones as well.
Bones involved in the formation of face
- The face consists of fourteen bones that fuse to give the specific shape of the face. The bones involved in the formation of the face are the two inferior nasal conchae, two nasals, two zygomatic, two lacrimals, vomer, maxilla, mandible, and palatine. The facet bone fusionof these bones occurs and the face is formed.
- The two slender nasal bones form the bridge of the nose and the inferior nasal conchae is present in the nasal cavity. Their main function is to increase the surface area of the nasal cavity so that the amount of air flowing inside the nose is more and the air that comes in contact with the mucous lining of the nasal cavity is also more so that the air is humidified and filtered before they go inside the body.
- The two zygomatic bones fuse to form the cheek and they also contribute to the formation of the orbits for the eyes.
- The two lacrimal bones are the smallest bone in the face and they form the medial portion of the orbit that later on forms the space for the lacrimal glands.
- The vomer is a thin, unpaired bone in the face that attaches to the skull as well as attaches to the band that helps to shape the nose and face.
- The maxillary bones fuse in the midline of the face and form the upper jaw that forms the space for the teeth in the upper jaw, floor for the nose, and orbits. This articulates with the zygomatic, nasal, lacrimal, and palatine bones to contribute to the formation of the other facial structures.
- The mandible forms the lower jaw in the face and creates a space for the teeth to develop in the lower jaw. It is movable, therefore, only the lower jaw of the face can move and not the upper jaw.
- The palatine bones fused in the midline of the face to form the palatine at the back of the nasal cavity to form the roof of the mouth and the floor of the orbit.
- All these bones in the face fuse together to form the structure of the face. Later on, muscles develop on the frame to give a particular shape to the face.
However, there are chances that the fusion of the bones may not be correct and then there may be the formation of some other features in the face.
Cheek dimples and chin dimples are the best examples of that. However, there are also chances of some such features that may be problematic. In case of that, there is an option of facet bone fusion surgery that anyone can opt for at an affordable price.
