Muscle that depresses the epiglottis (M. Depressor Epiglottidis)

The depressor supra gorgaonicus muscle consists of striated muscle fibers, the sarcolemma does not contain nerve endings, has an outlet in the center of the muscle, and the fibers also exit the submucosal layer of the vocal cords. This muscle causes the epiglottis plate to slide down and forward. This muscle ensures the closure of the glottis when swallowing food and speech, narrows the lumen of the digestive canal in its initial part, and performs the lowering function of the epiglottis during the oral phase of the respiratory process. The levator esophagus muscle arises from the lower part of the sternum, goes up to the diaphragm, passes through the thoracoaortic septum and attaches to the distal part of the esophagus, displacing it upward.
