The laryngeal part of the pharynx, also known as para laryngea (pharyngis), PNA, BNA, para laryngica, JNA, hypopharynx or laryngopharynx, is the lower part of the pharynx from the level of the upper edge of the epiglottis to the beginning of the esophagus. It is located on the anterior wall of the pharynx and is the entrance to the larynx.
The laryngeal part of the pharynx plays an important role in the process of swallowing food and breathing. During swallowing, food passes through the laryngeal part of the pharynx and enters the esophagus. When breathing, air passes through the laryngeal part of the pharynx and goes to the lungs.
Anatomically, the laryngeal portion of the pharynx consists of several parts, including the epiglottis, epiglotis, larynx, and laryngeal ring. The epiglottis is located above the larynx and plays an important role in sound production. The epiglotis is located at the top of the larynx and closes the entrance to the lower airway during swallowing to prevent food from entering the lungs.
The laryngeal ring is made up of cartilage that forms the structure of the larynx. It contains the vocal cords, which allow us to produce sounds when air passes through the larynx. The laryngeal part of the pharynx also contains many small muscles that help control swallowing and breathing.
Despite the fact that the laryngeal part of the pharynx plays a key role in our lives, it can also become the site of various diseases. Laryngeal cancer, tumors, infections and other pathologies can lead to dysfunction of the laryngeal part of the pharynx and require medical intervention.
Thus, the laryngeal part of the pharynx is an important anatomical structure that plays a decisive role in the processes of swallowing and breathing. Its role in sound production also makes it key to our ability to communicate. This part of the pharynx can become the site of various pathologies that require careful medical monitoring and treatment.
Laryngeal part of the pharynx (Pars laryngea pharyngis, PNA, BNA; Pars laryngica JNA; synonym: Hypopharynx Laryngopharynx)
The laryngeal part of the pharynx is the lower part of the pharynx, from the level of the upper edge of the epiglottis to the beginning of the esophagus. It is located on the back wall of the pharynx and has the shape of a triangle. On the anterior wall of the laryngeal part of the pharynx there is an entrance to the larynx, which is an important anatomical formation, since air passes through it during breathing.
The laryngeal part of the pharynx also contains lymph nodes, which are involved in protecting the body from infections and other diseases. In addition, this area contains the muscles responsible for the movement of the larynx and pharynx.
Diseases of the laryngeal part of the pharynx can cause a number of problems, such as cough, hoarseness, difficulty breathing and other symptoms. In such cases, it is necessary to consult a doctor to diagnose and treat the disease.
Thus, the laryngeal part of the pharynx is an important part of the pharyngeal apparatus and plays an important role in the functioning of the body.
