The tragus muscle (lat. Musculus trágicus) is a thin and long muscle that is located on the lateral surface of the pharynx and is involved in the formation of the lateral wall of the pharyngeal cavity, as well as in the formation and closure of the auditory tube. This muscle is one of the smallest muscles in the human body, its length is only about 1-2 cm.
The tragus muscle starts from the external auditory canal at the base of the tragus (the part of the ear located on the border between the pinna and the external auditory canal) and runs up and back along the side wall of the pharynx, where it connects with other muscles such as the pharyngeal muscle and the muscles of the pharyngeal wall . During contraction of the tragus muscle, the auditory tube closes, which protects the middle ear from air and liquid entering during swallowing.
In addition, the tragus muscle is also involved in the formation of the lateral border of the pharyngeal cavity and the formation of the pharyngeal reflex, which helps a person swallow food and liquids.
However, like any other muscle in the body, the tragus muscle can be subject to various diseases and pathologies, such as injury, infection and tumors. In such cases, surgery may be required to remove the tumor or restore muscle function.
Overall, the tragus muscle is an important muscle in the human body and plays an important role in protecting the middle ear and pharyngeal cavity. However, if any problems occur with this muscle, it is necessary to see a doctor for diagnosis and treatment.
