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 nasion (/ ˈ n eɪ z i ɒ n /) is the most anterior point of the frontonasal suture that joins the nasal part of the frontal bone and the nasal bones.It marks the midpoint at the intersection of the frontonasal suture with the internasal suture joining the nasal bones. [1]
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]
It meets the nasal bone where it presents a rough, uneven serrated notch known as the nasal notch, and this articulates on either side of the middle line with the nasal bone, and laterally with the frontal process of the maxilla and with the lacrimal. This part is sometimes called the nasal part of frontal bone.
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 ...
Frontal sinus fractures occur from trauma to the part of the frontal bone that overlies the sinus, often from motor vehicle accidents and falls. The hallmarks of a frontal sinus fracture is a frontal depression in the anterior table of the bone.
The nasal bones are two small oblong bones, varying in size and form in different individuals; they are placed side by side at the middle and upper part of the face and by their junction, form the bridge of the upper one third of the nose. Each has two surfaces and four borders.
The frontal bone and the parietal bones are joined at the frontal suture. The frontal bone has a number of parts, including the squamous part, the orbital part, and the nasal parts. The frontal bone connects to the parietal bone at the coronal suture to shape the crown and sides of the skull. The two separate parietal bones are joined at the ...
