Applied anatomy and oral surgery for dental students . e, is the anterior palatine fossa, whichcontains four openings, two being the foramina ofScarpa, situated anteroposteriorly, and transmitting thenasopalatine nerves, and two situated laterally, theforamina of Stenson, transmitting the anterior palatinevessels. In the suture between the maxilla and thepalate bone are the posterior and accessory palatinecanals, for the transmission of the posterior palatinenerves and vessels. The Nasal Fossae The nasal fossae, two in number, are situated one oneither side of the median line of the face, separated bya thin plate of bone—the nasal septum. The nasalfossae are composed of a roof, a floor, a septum, andouter walls. The roof of the nasal fossas consists of three portions—anterior, middle, and posterior. The anterior por-tion extends upward and backward, and is composed ofthe under surfaces of the nasal bones and the nasalspine of the frontal bone. The middle portion is hori-zontal, and is composed of the cribriform plate of the £OiVES 35. 36 APPLIED ANATOMY ethmoid bone. The posterior portion slopes downwardand backward, and is composed of the body of the sphe-noid and the alae of the vomer. The floor of the nose is formed by the palatal processesof the maxillae in front and the horizontal processes ofthe palate bones behind. The septum of the nose lies vertically in the medianline and runs in an anteroposterior direction. Theprincipal structures forming it are the vomer behind andbelow, the vertical plate of the ethmoid in front andabove, while in the recent state a triangular notch infront is filled in with the triangular cartilage. In addi-tion, the crests of the maxillary and palate bones, therostrum of the sphenoid, and the nasal spine of thefrontal bones assist in forming the nasal septum (Fig. 8). The bones entering into the formation of the lateralwall of the nasal chamber are: the nasal, the nasal processof the maxillary, the lacrimal, the ethmoid, the inf
