The aryepiglotticus muscle is a special muscle that is usually counted among the muscles of the larynx. The aryepiglotticus muscle is comparatively small and shallow. In principle, it is one of the inner muscles of the larynx area.

What is the muscular aryepiglotticus?

The muscular aryepiglotticus belongs to the so-called laryngeal musculature. Specifically, the muscle is located in the inner region of the laryngeal muscles. As a rule, it is a relatively small and tender muscle.

The aryepiglotticus muscle originates from the upper area of ​​the so-called arytenoid cartilage. This cartilage is commonly referred to in medical terminology as Cartilago arytaenoidea. In its further course, the aryepiglotticus muscle moves to the so-called plica aryepiglottica. This is located on the lateral portion of the epiglottis. In principle, the aryepiglotticus muscle continues the arytaenoideus obliquus muscle.

Anatomy & Construction

The aryepiglotticus muscle is located near the human larynx. Because the aryepiglotticus muscle is an essential element of the internal muscles of the larynx. For this reason, the aryepiglotticus muscle is located in the front of the neck. The size of the aryepiglotticus muscle is comparatively small. In addition, the muscle is relatively thin and narrow in shape.

The aryepiglotticus muscle is usually innervated by two special nerves. These two nerves are on the one hand the so-called inferior laryngeal nerve and the recurrent laryngeal nerve. It should be noted that the laryngeal nerve originates from the recurrent laryngeal nerve. Basically, the aryepiglotticus muscle is closely related to numerous other muscles of the laryngeal muscles. Disturbances in the sensitive system of the laryngeal musculature, for example, impair the voice of the affected persons. The respective complaints are noticeable in individual cases by a variety of typical symptoms.

Function & Tasks

The aryepiglotticus muscle performs various important functions and functions in connection with the internal musculature of the larynx. In this way, the aryepiglotticus muscle contributes to the functioning of the vocal tract. Basically, the aryepiglotticus muscle causes a narrowing at the beginning of the larynx. This area is called with medical terminology Aditus laryngis. In addition, the aryepiglotticus muscle promotes the usual movements of the epiglottis in a certain direction.

Basically, the most important functions of the muscular aryepiglotticus are on the one hand in the so-called Deglutation and on the other hand in the phonation. Deglutation is primarily the process of swallowing, such as saliva or food. As part of the laryngeal elevation during swallowing, the epiglottis is lowered, moving over the entrance of the larynx. This process comes in particular by two triggers to conditions. On the one hand, the reason for the tongue shifts to the back during the swallowing process. On the other side, the thyrohyoid muscle contracts. Special fibers of the muscular aryepiglotticus cause the vestibule of the larynx to narrow. In addition, the epiglottis and the arytenoids move towards each other.

Also in connection with phonation the aryepiglotticus muscle plays an important role. Here, the aryepiglotticus muscle performs important tasks in the anterior tension chain. It is an arrangement of certain muscles that together make for a narrowing and closing of the so-called vocal tract. As the epiglottis and the arytenoids approach each other, the vocal folds shorten. In this way, the effect of the vocalis muscle is weakened. In addition, the effect of the cricothyroid muscle is increasing.

To compensate for this, it is necessary for the vocalis muscle to regulate both the voice frequency and the volume. To do so, the muscle would have to make enormous efforts. As a result, under certain circumstances, a so-called oval Glottisspalt forms. The narrowing of the vestibule is required for certain types of chants. The narrowing effect of the muscular aryepiglotticus is necessary, for example, when singing with a loud voice.

Diseases

In connection with the muscular aryepiglotticus, various clinical pictures and complaints are possible, which in some persons result in certain circumstances.

Since the aryepiglotticus muscle is an integral part of the internal muscles of the larynx, injury or impairment of any other kind adversely affects the voice of the affected person. Because the larynx represents the most important vocal organ of the human organism. Disturbances in the sensitive interaction of the individual muscles and nerves, which are in the area of ​​the larynx, possibly lead to considerable difficulties of the voice.

Apart from the immediate effect on the voice in case of impairment of the aryepiglotticus muscle, disorders of the muscle may also cause problems with the swallowing process. For in the process of swallowing, the aryepiglotticus muscle takes over essential tasks in the area of ​​the larynx. In principle, all complaints in connection with the laryngeal musculature should be clarified by a suitable doctor as soon as possible.

Because an exact diagnosis and a timely treatment remain, sometimes cause chronic discomfort to the muscles of the larynx. The complex interaction of the laryngeal musculature and the aryepiglotticus muscle must be protected in the event of illness by adequate therapy measures and protection of the voice.
