The vomer (/ ˈ v oʊ m ər /; [1] [2] Latin: vomer, lit. 'ploughshare') 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.
The septal nasal cartilage fits in a place between the perpendicular plate of the ethmoid and vomer bones while also being covered by an internal mucous membrane. The superior portion of the septal nasal cartilage attaches to the nasal bones, while the inferior portion attaches to the alar cartilages via fibrous tissues.
A major disadvantage of the vomer flap surgery is the varying size and visibility of the vomer in different patients. If the vomer is not visible or too small to cover the cleft, the procedure cannot be done. Another disadvantage of the use of the vomer flap in the oral cavity is that the vomer tissue does not aesthetically match the oral mucosa.
All major bones, muscles, and nerves in the body are named, with the exception of anatomical variations such as sesamoid bones and accessory muscles. Blood vessels carry blood throughout the body, which moves because of the beating of the heart. Venules and veins collect blood low in oxygen from tissues throughout the body.
The vomer bone is much shorter in length than it is in other amphibamids, but similar in proportion to living amphibians. As in most frogs, the palatine bone forms a narrow strip along the side of the palate. Gerobatrachus possesses another modern amphibian characteristic at the back of the skull, a widened bone called the parasphenoid basal
Vomer bone The lowest part of the septum is a narrow strip of bone that projects from the maxilla and the palatine bones , and is the length of the septum. This strip of bone is called the maxillary crest; it articulates in front with the septal nasal cartilage, and at the back with the vomer. [ 5 ]
The name is derived from the fact that it lies adjacent to the unpaired vomer bone (from Latin vomer 'plowshare', for its shape) in the nasal septum. It is present and functional in all snakes and lizards, and in many mammals, including cats, dogs, cattle, pigs, and some primates.
The parasphenoid is a bone which can be found in the cranium of many vertebrates.It is an unpaired dermal bone which lies at the midline of the roof of the mouth. In many reptiles (including birds), it fuses to the endochondral (cartilage-derived) basisphenoid bone of the lower braincase, forming a bone known as the parabasisphenoid.
