Bashline Clinic If your sphenoid bone is locked, your body will balance itself by twisting or turning some other part of your body (like your spine or your head) to maintain stability. The sphenoid bone was designed by our creator to stay balanced at all times, like a compass always wanting to point north, otherwise we would not stay upright. The NCR doctor monitors the position of the sphenoid closely throughout the treatments since each inflation changes the picture. www.ncrdoctor.info   (529 words)

Maxilla - Wikipedia, the free encyclopedia At the lower part of this surface is a rounded eminence, the maxillary tuberosity, especially prominent after the growth of the wisdom tooth; it is rough on its lateral side for articulation with the pyramidal process of the palatine bone and in some cases articulates with the lateral pterygoid plate of the sphenoid. Each bone consists of a body and four processes - zygomatic, frontal, alveolar, and palatine. The frontal process is well-marked and the body of the bone consists of little more than the alveolar process, the teeth sockets reaching almost to the floor of the orbit. en.wikipedia.org /wiki/Maxilla   (2426 words)

They are separated from one another by the vomer, and each is bounded above by the body of the sphenoid, below by the horizontal part of the palatine bone, and laterally by the medial pterygoid plate of the sphenoid. The surface is traversed by three sutures, viz.: (1) the coronal sutures, nearly transverse is direction, between the frontal and parietals; (2) the sagittal sutures, medially placed, between the parietal bones, and deeply serrated in its anterior two-thirds; and (3) the upper part of the lambdoidal suture, between the parietals and the occipital. The squamosal suture arches backward from the pterion and connects the temporal squama with the lower border of the parietal: this suture is continuous behind with the short, nearly horizontal parietomastoid suture, which unites the mastoid process of the temporal with the region of the mastoid angle of the parietal. www.bartleby.com /107/46.html   (668 words)

The lateral wall of the nose is separated from the maxilla by the perpendicular plate of the palatine bone.
