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 ...
The carina is a cartilaginous ridge separating the left and right main bronchi that is formed by the inferior-ward and posterior-ward prolongation of the inferior-most tracheal cartilage. [2] The carina occurs at the lower end of the trachea - usually at the level of the 4th to 5th thoracic vertebra.
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.
The trachea, sometimes called the windpipe, is actually a series of C-shaped cartilage rings which are connected by a thin layer of smooth muscle called the trachealis muscle and a connective tissue membrane. It runs from your larynx, or voice box, to a structure called the carina.
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).
