Larynx

The larynx is a hollow organ located between the pharynx and trachea. It consists of several cartilages, articulated with each other, lined with mucous membrane and driven by muscles. At its top is the epiglottis, a valve that closes the larynx when it absorbs food. In the middle section, called the vocal apparatus, there are small elastic muscles - the vocal cords. They are the main sound-producing organ: when air leaves the lungs and passes through the larynx, its muscles stretch the vocal cords, which vibrate and form the voice. Cartilaginous formation located in front of the trachea; acquired the function of the vocal apparatus for the second time.

The larynx, also known as the larynx, is an organ of the human respiratory and speech system. It is located between the pharynx and trachea, and performs several important functions related to breathing and pronunciation of sounds.

Anatomically, the larynx is a collection of cartilage connected by ligaments, muscles and other tissues. It has the shape of a triangular prism and is about 5 cm in length in an adult. The larynx is composed of several important structures, including the vocal cords, vocal apparatus, epiglottis, and inferior laryngeal cover.

One of the main functions of the larynx is to allow air to pass into the lungs. When you inhale, air passes through the nose or mouth, then passes through the larynx and is sent further to the trachea and lungs. The larynx also has a protective function, preventing food or other foreign objects from entering the airways. This is achieved by the epiglottis, a small valve that closes to seal off the entrance to the larynx during swallowing.

The larynx also plays an important role in the production of sounds and speech production. The vocal cords, located inside the larynx, control the production of sound. When making sounds, the vocal cords vibrate, creating sound vibrations, which are then formed into intelligible speech in cooperation with other organs such as the lips, tongue and teeth.

Some diseases and disorders can affect the functioning of the larynx and a person's ability to speak and breathe normally. For example, inflammation of the larynx (laryngitis) can cause changes in the voice and difficulty breathing. Laryngeal cancer is also a serious disease that can cause problems with speech and breathing.

In conclusion, the larynx plays an important role in the human respiratory and speech system. It allows air to pass into the lungs, protects the airways from foreign objects, and helps produce sounds for speech. Understanding the anatomy and function of the larynx is an important aspect of human health and communication.
