The septum generally stays in the midline until about the age of seven, at which point it will frequently deviate to the right. An operation to straighten the nasal septum is known as a septoplasty. A perforated nasal septum can be caused by an ulcer, trauma due to an inserted object, long-term exposure to welding fumes, [6] or cocaine use ...
The perpendicular plate of the ethmoid bone (vertical plate) is a thin, flattened lamina, polygonal in form, which descends from the under surface of the cribriform plate, and assists in forming the septum of the nose; it is generally deflected a little to one or other side. The anterior border articulates with the spine of the frontal bone and ...
The nasal cavity is divided in two by the vertical nasal septum. On the side of each nasal cavity are three horizontal outgrowths called nasal conchae (singular "concha") or turbinates. These turbinates disrupt the airflow, directing air toward the olfactory epithelium on the surface of the turbinates and the septum.
The anterior surface of the body [Fig. 2] presents, in the middle line, a vertical crest, the sphenoidal crest, which articulates with the perpendicular plate of the ethmoid, and forms part of the nasal septum. On either side of the crest is an irregular opening leading into the corresponding sphenoidal air sinus.
The septum grows down from the roof of the nasal cavity and fuses with the developing palates along the midline. The septum divides the nasal cavity into two nasal passages opening into the pharynx through the definitive choanae. [48] [49] At ten weeks, the cells differentiate into muscle, cartilage, and bone.
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.
Interventricular septum, the wall separating the left and right ventricles of the heart [2] Lingual septum, a vertical layer of fibrous tissue that separates the halves of the tongue [3] The lingual septum can be seen running vertically through the center of the tongue. Nasal septum: the cartilage wall separating the nostrils of the nose [4]
On average, a sphenoid sinus measures 2.2 cm vertical height, 2 cm in transverse breadth; and 2.2 cm antero-posterior depth. [3] Each spehoid sinus is in the body of sphenoid bone, just under the sella turcica. The sphenoid sinuses are separated from each other medially by the septum of sphenoidal sinuses, which is usually asymmetrical.
