";s:4:"text";s:4452:"The superior border, the thickest, presents a deep furrow, bounded on either side by a horizontal projecting expansion of bone – called the wing of vomer; the furrow receives the rostrum of the sphenoid, while the margins of the alae articulate with the vaginal processes of the medial pterygoid plates of the sphenoid behind, and with the sphenoidal processes of the palatine bones in front. The body of the sphenoid bone, more or less cubical in shape, is hollowed out in its interior to form two large cavities, the sphenoidal sinuses, which are separated from each other by a septum. I. Embryology II. The anterior border is the longest and slopes downward and forward. The sphenoidal conchae are two thin, curved plates, situated at the anterior and lower part of the body of the sphenoid. (Vomer visible at bottom left. Osteology III. Syndesmology IV. In bony fish, the vomers are flattened, paired, bones forming the anterior part of the roof of the mouth, just behind the premaxillary bones. They are typically small in birds, where they form the upper hind part of the beak, again being located between the choanae. The vomer (/ ˈ v oʊ m ər /) is one of the unpaired facial bones of the skull.It is located in the midsagittal line, and articulates with the sphenoid, the ethmoid, the left and right palatine bones, and the left and right maxillary bones. It is thin, somewhat quadrilateral in shape, and forms the hinder and lower part of the nasal septum; it has two surfaces and four borders. The vomeronasal organ, also called Jacobson's organ, is a chemoreceptor organ named for its closeness to the vomer and nasal bones, and is particularly developed in animals such as cats (who adopt a characteristic pose called the Flehmen reaction or flehming when making use of it), and is thought to have to do with the perception of certain pheromones. Hence, these two are considered as a part of the cranial bones. An aperture of variable size exists in the anterior wall of each, and through this the sphenoidal sinus opens into the nasal cavity. Right side. The posterior border is free of bony articulation, having no muscle attachments. It is concave, separates the choanae, and is thick and bifid above, thin below. The inferior border articulates with the crest formed by the maxillæ and palatine bones. It is concave, separates the choanae, and is thick and bifid above, thin below. The vomer forms the inferior part of the nasal septum, with the superior part formed by the perpendicular plate of the ethmoid bone. The greater wing of the sphenoid bone, or alisphenoid, is a bony process of the sphenoid bone; there is one on each side, extending from the side of the body of the sphenoid and curving upward, laterally, and backward. The upper jaw includes the hard palate in the front of the mouth. It is situated in the middle of the skull towards the front, in front of the temporal bone and the basilar part of the occipital bone. They also take waste and carbon dioxide and carry them away from the tissues and back to the heart. It is thin, somewhat quadrilateral in shape, and forms the hinder and lower part of the nasal septum; it has two surfaces and four borders. The vomer is situated in the median plane, but its anterior portion is frequently bent to one side. In anatomy, the term rostrum is used for a number of phylogenetically unrelated structures in different groups of animals. The lacrimal bone is a small and fragile bone of the facial skeleton; it is roughly the size of the little fingernail. These vessels are designed to transport nutrients and oxygen to the tissues of the body. The surfaces are marked by small furrows for blood vessels, and on each is the nasopalatine groove, which runs obliquely downward and forward, and lodges the nasopalatine nerve and vessels. It also articulates with the septal cartilage of the nose. Injury or fracture of the lacrimal bone can result in posttraumatic obstruction of the lacrimal pathways. The cubical bone is lightweight due to a spongy construction. It forms the anterior three quarters of the hard palate, the horizontal plate of the palatine bone making up the rest. Right side. Osteology > The Vomer TABLE OF CONTENTS. These are the vertically oriented squamous part, and the horizontally oriented orbital part, making up the bony part of the forehead, part of the bony orbital cavity holding the eye, and part of the bony part of the nose respectively.
