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 human nose is the first organ of the respiratory system.It is also the principal organ in the olfactory system.The shape of the nose is determined by the nasal bones and the nasal cartilages, including the nasal septum, which separates the nostrils and divides the nasal cavity into two.
The interventricular septum (IVS, or ventricular septum, or during development septum inferius) is the stout wall separating the ventricles, the lower chambers of the heart, from one another. The interventricular septum is directed obliquely backward to the right and curved with the convexity toward the right ventricle ; its margins correspond ...
A coral septum is one of the radial calcareous plates in the corallites of a coral. [18]Annelids have septa that divide their coelom into segmented chambers. [19]Many shelled organisms have septa subdividing their shell chamber, including rhizopods, cephalopods and gastropods, the latter seemingly serving as a defence against shell-boring predators.
The nasal septum divides the cavity into two cavities, [1] also known as fossae. [2] Each cavity is the continuation of one of the two nostrils. The nasal cavity is the uppermost part of the respiratory system and provides the nasal passage for inhaled air from the nostrils to the nasopharynx and rest of the respiratory tract.
With a crooked septum, it is more difficult for an individual to breathe and the risk for getting a sinus infection increases. Also called a deviated septum, a crooked nose will block one or both sides of the nose, affecting the quality of life. [4] However, a deviated septum is very common and does not always create respiratory issues.
Kiesselbach's plexus is an anastomotic arterial network (plexus) of four or five arteries in the nose supplying the nasal septum. It lies in the anterior inferior part of the septum known as Little's area, Kiesselbach's area, or Kiesselbach's triangle. It is a common site for anterior nosebleeds.
Large-gauge septum piercing Fulani woman with traditional nose ring and mouth tattooThe nasal septum is the cartilaginous dividing wall between the nostrils. Generally, the cartilage itself is not pierced, but rather the small gap between the cartilage and the bottom of the nose (sometimes called the "sweet spot" by piercers), typically at 16g (1.2 mm) although it is often stretched to a ...
