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.
The sternal angle is used in the definition of the thoracic plane. [citation needed] The angle also marks the level of a number of features: Boundary between the superior and inferior portion of the mediastinum [citation needed] Passage of the thoracic duct from right to left behind esophagus [citation needed] Tracheal bifurcation.
The larynx (voice box) and carina (at the bottom of the trachea, as it splits into bronchi) are especially sensitive. Cough receptors in the surface cells of the respiratory tract are also sensitive to chemicals. Terminal bronchioles and even the alveoli are sensitive to chemicals such as sulfur dioxide gas or chlorine gas. [1]
