Contents

There are two surfaces of the squama of the frontal bone: the external surface, and the internal surface. ... In human anatomy, the forehead or brow is the bony part of the head above the eyes. ... The orbital or horizontal part of the frontal bone (pars orbitalis) consists of two thin triangular plates, the orbital plates, which form the vaults of the orbits, and are separated from one another by a median gap, the ethmoidal notch. ... The nasal cavity (or nasal fossa) is a large air-filled space above and behind the nose in the middle of the face. ...


Borders

The border of the squama is thick, strongly serrated, bevelled at the expense of the inner table above, where it rests upon the parietal bones, and at the expense of the outer table on either side, where it receives the lateral pressure of those bones; this border is continued below into a triangular, rough surface, which articulates with the great wing of the sphenoid. The posterior borders of the orbital plates are thin and serrated, and articulate with the small wings of the sphenoid. The sphenoid bone (os sphenoidale) is a bone situated at the base of the skull in front of the temporals and basilar part of the occipital. ...


Structure

The squama and the zygomatic processes are very thick, consisting of diploic tissue contained between two compact laminæ; the diploic tissue is absent in the regions occupied by the frontal air sinuses. The orbital portion is thin, translucent, and composed entirely of compact bone; hence the facility with which instruments can penetrate the cranium through this part of the orbit; when the frontal sinuses are exceptionally large they may extend backward for a considerable distance into the orbital portion, which in such cases also consists of only two tables. Lamina may refer to: Planar lamina, a 2 dimensional planar closed surface with mass and density (mathematics). ...

II. Osteology. 5a. 3. The Frontal Bone. Gray, Henry. 1918. Anatomy of the Human Body. (1319 words)
The frontal bone resembles a cockle-shell in form, and consists of two portions—a vertical portion, the squama, corresponding with the region of the forehead; and an orbital or horizontal portion, which enters into the formation of the roofs of the orbital and nasal cavities.
The superior surface is convex, and marked by depressions for the convolutions of the frontal lobes of the brain, and faint grooves for the meningeal branches of the ethmoidal vessels.
The anterior canal transmits the nasociliary nerve and anterior ethmoidal vessels, the posterior, the posterior ethmoidal nerve and vessels.
Ethmoid bone - Wikipedia, the free encyclopedia (1276 words)
The ethmoid bone (os ethmoidale) is a bone in the skull that separates the nasal cavity from the brain.
The ethmoid bone (os ethmoidale) is exceedingly light and spongy, and cubical in shape; it is situated at the anterior part of the base of the cranium, between the two orbits, at the roof of the nose, and contributes to each of these cavities.
The anterior border articulates with the spine of the frontal bone and the crest of the nasal bones.
