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.
Changes indicative of disease are seen as alterations in the oral mucosa lining the mouth, which can reveal systemic conditions, such as diabetes or vitamin deficiency, or the local effects of chronic tobacco or alcohol use. [3] The oral mucosa tends to heal faster and with less scar formation compared to the skin. [4]
Mouth and genital ulcers with inflamed cartilage syndrome or MAGIC syndrome is a condition in which an individual exhibits symptoms of both relapsing polychondritis (RP) and Behcet's disease (BD). [1] Inflammatory ulcers in the mouth, genitalia, and skin are the hallmark of Behcet's disease (BD), a multisystem illness that is chronic and ...
The trachea begins at the lower edge of the cricoid cartilage of the larynx [3] at the level of sixth cervical vertebra (C6) [2] and ends at the carina, the point where the trachea branches into left and right main bronchi., [2] at the level of the fourth thoracic vertebra (T4), [2] although its position may change with breathing.

Skin is in! There have been no shortage of wardrobe malfunctions in 2017, and we have stars like Bella Hadid, Chrissy Teigen and Courtney Stodden to thank for that.
Cartilage is present until the bronchioles. In the trachea, they are C-shaped rings of hyaline cartilage, whereas in the bronchi the cartilage takes the form of interspersed plates. Smooth muscle starts in the trachea, where it joins the C-shaped rings of cartilage. It continues down the bronchi and bronchioles, which it completely encircles ...
Dental radiographs, commonly known as X-rays, are radiographs used to diagnose hidden dental structures, malignant or benign masses, bone loss, and cavities.. A radiographic image is formed by a controlled burst of X-ray radiation which penetrates oral structures at different levels, depending on varying anatomical densities, before striking the film or sensor.
