Muscle, Hyopharyngeal (M. Hyopharyngicus, Jna)

This article discusses the Hyoid Pharyngeal muscle (its more official name is M. Hyopharynx Glottis), which plays a key role in creating and maintaining the correct functional functioning of the pharynx and larynx. This muscle connects the submandibular and sublingual salivary glands to the esophagus, and its main function is to voluntarily hold pieces of food between the anterior 2/3 of the esophagus and the posterior wall of the esophagus.

The hypoglossal pharyngeal muscle M. Hyopharyngeus consists of a group of striated muscle fibers that originate from the muscular processes of the lower jaw (myotome mandibula), emerging from the retropharyngeal ring muscles, attaching to the base of the tongue.

In the larynx, the laryngeal diaphragm and the medial thyroid muscle M. Saccaris Largo form the outer fascial layer and together form the thyroid diaphragm (fascia membrana thyreoglossalis). This fascial formation bears a number of muscles, including the unpaired superapical M. Cricothyreoglosus, plus the unpaired hypoglossal muscle of M. Hyropharyngeus.

The laryngeal muscles of M. Thyreoglosis are also divided into superior and inferior, each with its own names and functional importance. The upper group consists of 3 muscles: the large vocalis M. Laryngeae Luscus, the middle vocalis M. Vesliricus Vulgaris and the small vocalis m. Arnctie. The lower group includes the vocal larynxes M. boticolii and Sustatricularis, which act on the vocal cords to produce the sound of the voice.

In addition, once the vocal comglottis becomes deficient due to fatigue or illness, the lingual muscle immediately becomes active to help compensate for this loss of the vocal comglottis. This allows patients to continue making sounds and remain in communication with the world. It is important to understand that constant tension in the muscles of the larynx can lead to pain and permanent damage.

Thus, the Hyoid Pharyngeal muscle plays an important role in maintaining the proper functioning of the larynx and pharynx. It has the ability to perform involuntary movements and allows us to participate in communication throughout our lives. However, if we frequently use the voice for long periods of time, we should be aware of the importance of using this muscle during voice exercises, in which we could compare its action with its importance in our daily life.
