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).
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 ...
19 Σεπ 2023 · The tracheal bifurcation houses a sagittally-oriented cartilaginous ridge called the carina. The right main bronchus is shorter, wider and courses almost vertically compared to the left one. Therefore, it is more susceptible to foreign body obstructions.
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.
15 Οκτ 2024 · The purpose of this article is to provide a review of tracheal anatomy. Included is a summary of tracheal embryology, tracheal structure and histology, arterial and venous blood supply, lymphatic drainage, and the relationships between the trachea and surrounding viscera.
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 begins at the lower border of the cricoid cartilage and extends to the level of the carina (Fig. 1). It is composed of C-shaped cartilaginous rings that form the anterior and lateral walls. The posterior membranous wall connects the arms of the “C” to form an ovoid tracheal lumen.
