The epipharynx is the upper part of the pharynx, which is located behind the epiglottis and is part of the larynx. The name comes from the Greek words "epi" (above) and "pharynx" (throat). The epipharynx is tube-shaped and connects the pharynx to the larynx.
The epipharynx performs several important functions in the human body. First, it protects the larynx from food and liquids. Secondly, it is involved in the formation of the voice. The epipharynx is part of the vocal apparatus, which consists of the larynx, vocal cords and the muscles that control their function.
The voice box is located at the back of the pharynx and consists of three parts: the larynx, the glottis and the vocal cords. The vocal cords are located at the front of the larynx and are two elastic folds that vibrate when sounds are made.
When a person speaks, his vocal cords vibrate, which produces sound. This process is controlled by the muscles, which are under the control of the nervous system. When nerve impulses pass through the vocal cords, they vibrate and create sound.
In a healthy body, the vocal cords work efficiently and ensure normal sound production. However, with some diseases, such as laryngitis, laryngotracheitis, pharyngitis and others, the vocal cords may become less effective. In such cases, medical attention may be required to restore normal functioning of the vocal apparatus.
Thus, the epipharynx plays an important role in producing sound and protecting the larynx from external influences. Its proper functioning is important for the health of the vocal apparatus and the general condition of the body.
