Human nose. 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 nasal septum contains bone and hyaline cartilage. [3] It is normally about 2 mm thick. [4] The nasal septum is composed of four structures: Maxillary bone (the crest) Perpendicular plate of ethmoid bone. Septal nasal cartilage (ie, quandrangular cartilage) Vomer bone. The lowest part of the septum is a narrow strip of bone that projects ...
Tracheal intubation, usually simply referred to as intubation, is the placement of a flexible plastic tube into the trachea (windpipe) to maintain an open airway or to serve as a conduit through which to administer certain drugs. It is frequently performed in critically injured, ill, or anesthetized patients to facilitate ventilation of the ...
Nasopharyngeal airway. In medicine, a nasopharyngeal airway, also known as an NPA, nasal trumpet (because of its flared end), or nose hose, is a type of airway adjunct, a tube that is designed to be inserted through the nasal passage down into the posterior pharynx to secure an open airway. It was introduced by Hans Karl Wendl [ de] in 1958. [1]
The depressor septi is a direct antagonist of the other muscles of the nose, drawing the ala of the nose downward, constricting the nostrils. It works like the alar part of the nasalis muscle. Clinical significance. During rhinoplasty, repositioning of the head of the depressor septi nasi muscle ensures normal nose position after surgery.

The nasal cycle is the unconscious [1] [2] alternating partial congestion and decongestion of the nasal cavities in humans and other animals. This results in greater airflow through one nostril with periodic alternation between the nostrils. It is a physiological congestion of the nasal conchae, also called the nasal turbinates (curled bony ...

The two wax rims are then notched in order to allow an index of the relationship of the maxillary rim to the mandibular rim with a medium, such as Alluwax or Regisal.
