Epiglottal Tubercle

Epiglottic tubercle: anatomy and functions

The epiglottic tubercle (tuberculum epiglotticum) is a small convex tubercle located at the top of the epiglottis (epiglotta), which is the middle part of the larynx. This tubercle is an important element of the anatomy of the respiratory and esophageal systems and also plays an important role in protecting the respiratory tract.

Anatomy of the supraglottic tubercle

The epiglottis is located at the top of the epiglottis. The epiglottic cartilaginous cap (epiglotta) is located above it, and the vocal cords and epiglottis muscle are located below it.

Functions of the supraglottic tubercle

One of the main functions of the supraglottic tubercle is to protect the respiratory tract. When we swallow food, a cartilaginous cap (epiglotta) closes the entrance to the airways to prevent food particles from entering the lungs. The supraglottic tubercle helps keep the epiglotta in the correct position to provide effective airway protection.

In addition, the supraglottic tubercle plays an important role in the production of sound during vocal pronunciation. It is one of the attachment points of the vocal cords and helps control their tension and length.

Disorders of the function of the supraglottic tubercle

Some diseases can lead to dysfunction of the supraglottic tubercle. For example, infections, injuries, or tumors can cause swelling and inflammation of the supraglottic region, which can impair the protective function of the epiglott and airways. This can lead to problems swallowing, coughing, shortness of breath and other symptoms.

In conclusion, the supraglottic tubercle plays an important role in protecting the airway and producing sound during vocal production. Although it can be subject to various dysfunctions, in general it is an important element of the anatomy of the respiratory and esophageal system.

The epiglottis, or hypopharynx (hypopharynx), is a small fold of the mucous membrane of the posterior part of the pharynx and passes to its lateral free edge. The epiglottic fold is penetrated by many folds, which include the main and subordinate vestibulopharyngeal, periglottic folds
