Information about Nasal Septum
| Bones and cartilages of septum of nose. Right side. | |
| Latin | septum nasi |
| subject #223 993 | |
| Artery | anterior ethmoidal posterior ethmoidal sphenopalatine greater palatine branch of superior labial[1] |
| Nerve | anterior ethmoidal nasopalatine[1] |
| MeSH | Nasal+septum |
| Dorlands/Elsevier | s_08/12730490 |
It is depressed by the Depressor septi nasi muscle.
Composition
The fleshy external end of the nasal septum is sometimes also called columella.The nasal septum is composed of three structures:
Clinical significance
The nasal septum can depart from the centreline of the nose; this condition is known as a deviated septum. Trauma, excessive nose-picking and cocaine usage can cause septum perforations, or holes developing in the septum.An operation to the nasal septum is known as a septoplasty.

nose is a protuberance in vertebrates that houses the nostrils, or nares, which admit and expel air for respiration in conjunction with the mouth.
In most humans, it also houses the nosehairs, which catch airborne particles and prevent them from reaching the lungs.

Septoplasty is a corrective surgical procedure done to straighten the nasal septum - the partition between the two nasal cavities. Ideally, the septum should run down the center of the nose. When it deviates into one of the cavities, it narrows that cavity and impedes airflow.
