The frontal process of the maxilla is a strong plate, which projects upward, medialward, and backward from the maxilla, forming part of the lateral boundary of the nose. Its lateral surface is smooth, continuous with the anterior surface of the body, and gives attachment to the quadratus labii superioris , the orbicularis oculi , and the medial ...
The frontal bone is one of the principal paired mid-line bones in dinosaur skulls. This bone is part of the skull roof, which is a set of bones that cover the brain, eyes and nostrils. The frontal makes contact with several other bones in the skull. The anterior part of the bone articulates with the nasal bone and the prefrontal bone. The ...
The anterior nasal spine, or anterior nasal spine of maxilla, is a bony projection in the skull that serves as a cephalometric landmark. [1] The anterior nasal spine is the projection formed by the fusion of the two maxillary bones at the intermaxillary suture.
The nasal process ends below in a sharp spine, and on either side of this is a small grooved surface which enters into the formation of the roof of the corresponding nasal cavity. The spine forms part of the septum of the nose, articulating in front with the crest of the nasal bones and behind with the perpendicular plate of the ethmoid.
The topmost bony part of the nose is formed by the nasal part of the frontal bone, which lies between the brow ridges, [3] and ends in a serrated nasal notch. [4] A left and a right nasal bone join with the nasal part of the frontal bone at either side; and these at the side with the small lacrimal bones and the frontal process of each maxilla. [3]
Frontal bone fractures may result in damage to the frontonasal duct, resulting in impaired drainage of the frontal sinus and consequent predisposition to intercranial spread of infection, and the development of mucocele in the frontal sinus. Frontal sinus wall fractures may require the frontonasal duct to be sealed and the epithelium of the ...

the cranium (8 bones: frontal, 2-parietal, occipital, 2-temporal, sphenoid, ethmoid), and; the facial bones (14 bones: 2-zygomatic, 2-maxillary, 2-palatine, 2-nasal, 2-lacrimal, vomer, 2-inferior conchae, mandible). The occipital bone joins with the atlas near the foramen magnum, a large hole at the base of the skull. The atlas joins with the ...
