tracheal rings

The cartilages of the trachea (or tracheal rings) vary from sixteen to twenty in number.

Tracheal collapse is caused by a weakening of the tracheal rings in the windpipe.

The trachea of moa were supported by many small rings of bone known as tracheal rings.

The Annular ligaments of the trachea are circular horizontal fibrous bands that join the tracheal rings together.

The respiratory tube is also known in LACM 128319, preserved as cartilaginous tracheal rings.

Soft parts of its body, such as tracheal rings (cartilage) or remnants of skin were found, as well as single bones and complete skeletons.

The many possible complications include hemorrhage, loss of airway, subcutaneous emphysema, wound infections, stomal cellulites, fracture of tracheal rings, poor placement of the tracheotomy tube, and bronchospasm".

He refined the technique to be more similar to that used in modern times, recommending that a transverse incision be made between the third and fourth tracheal rings for the treatment of life-threatening airway obstruction.

Based on the available morphological and behavioural evidence, especially the structure of the humerus and the structure of tracheal rings, Sidney Dillon Ripley suggested that it was undoubtedly in the Aythyini.

The sole element still present consists of a seven millimetre long piece of the trachea of which about ten tracheal rings are visible, the most anterior of which are open at the top, giving them a C-shape.

Several types of tracheostomy tubes are available, depending on the requirements of the patient, including Shiley, Bivona (a silicon tube with metal rings that are good for airways with damage to the tracheal rings or otherwise not straight), and fenestrated.
