17 Απρ 2024 · The carina of the trachea is a cartilaginous projection of the last tracheal ring, found at the bifurcation of the trachea into the left and right main (primary/principal) bronchi. It lies in the sagittal plane and is located in line with the sternal angle, at the level of the fourth thoracic vertebra (T4).
19 Σεπ 2023 · The trachea is a D-shaped fibrocartilaginous respiratory organ. It consists of 16-20 tracheal cartilages anterolaterally and a fibromuscular wall posteriorly. The tracheal cartilages are composed of hyaline cartilage and interconnected by fibroelastic tissue.
The carina of trachea is a cartilaginous ridge within the trachea that runs antero-posteriorly between the two primary bronchi at the site of the tracheal bifurcation at the lower end of the trachea (usually at the level of the 5th thoracic vertebra, which is in line with the angle of Louis, but may raise or descend up to two vertebrae higher ...
31 Οκτ 2020 · At the bifurcation of the primary bronchi, a ridge of cartilage called the carina runs anteroposteriorly between the openings of the two bronchi. This is the most sensitive area of the trachea for triggering the cough reflex, and can be seen on bronchoscopy.
Structural anatomy. The trachea serves as a conduit for ventilation and the clearance of tracheal and bronchial secretions. The trachea begins at the lower border of the cricoid cartilage and extends to the level of the carina (Fig. 1).
