Muscle Laryngopharyngeus

Muscles of the larynx

**The muscular apparatus of the larynx is one of the most well-innervated formations.** All its muscles, from the lower to the upper, receive numerous (up to 20) endings from the vagus nerves: the superior laryngeal, the lower (or recurrent) laryngeal. This group of muscles also includes fibers and fascia of the hyoid bone, which are involved in closing the glottis. **The superior laryngeal nerve** descends down to meet the inferior laryngeal nerve, both nerves are separated from the overlying cricoid muscle by the hypoglossal process of the thyroid cartilage. Before applying to the cricoid

Muscles of the larynx

Laryngopharyngeus muscle (Latin musculus laryngopharyngeus), or Glottal frontal muscle (from ancient Greek λῆργξ - palate / pharynx + φάρυγχος - throat, pharynx; literally - “raising the palate”) - (abbr. MGM or LLFP) - skeletal muscle of the head and neck. It is located in the lateral wall of the pharynx and is closely adjacent to it. Below and medial to the thyroid gland, it begins from the pharyngotympanic membrane, and from behind it is attached to the anterior and lateral walls and posterior surface of the larynx, clasping it from below. Located under the transverse muscle of the pharynx. The levator palate action of the muscle leads to an increase in the volume of the pharyngeal cavity due to the elevation of the epiglottis and perichondrium along with the vocal fold. The outer (retroversion) and lower (laterversion) parts of the larynx in humans are associated with the facial muscles, while the apex of the angle (anterior-superior part of the larynx) is statically motionless.\n\nThe function of the laryngopharyngeal and subpharyngeal muscles consists of vertical movement (simultaneously lateral elevation of the soft palate and closing the glottis) and preventing asphyxia by the epiglottis. Together with other vocal muscles, the laryngopharyngeal muscles are involved in the formation of speech sounds. In case of severe narrowing of the airways (for example, with an allergy to ragweed), the muscles of the laryngopharynx, which are responsible for opening and closing the respiratory gap, may be weakened.\n\nSymptoms of overstrain of the laryngeal muscle are congestion in the cervical region, cough, hoarseness, etc. In various pathologies, the cause of swelling of the larynx is muscle contractions. Diseases can occur in a latent form and appear already in the last stages of the development of laryngospasm. Other possible complications and causes of laryngeal spasm are muscular dystrophy, Sjogren's disease, smoking, allergies, reflux esophagitis, tuberculosis, stridor.
