The pharyngotubal muscle (lat. m. pharyngotubalis, JNA) is a muscle that plays an important role in the process of swallowing and breathing. It is located in the pharynx and connects it with the auditory tube (Eustachian) - a canal that connects the middle ear with the pharynx.
The pharyngotubal muscle is tube-shaped and runs from the bottom of the skull to the edge of the pharynx. It consists of two sections: the palatine and the osteochondral. The palatal region starts from the base of the skull, runs along the larynx and ends at the level of the upper lip. The osteochondral section begins from the cartilage of the auditory tube and extends down to the edge of the pharynx.
This muscle plays an important role in the process of swallowing and breathing. During swallowing, it contracts and helps move food from the pharynx to the esophagus. During breathing, it opens the auditory tube, which allows you to equalize the pressure in the ear and prevent infections.
The pharyngotubal muscle also plays an important role in the process of balancing pressure in the ear. When the pressure in the middle ear decreases, the muscle contracts, opening the ear tube and allowing air from the pharynx to enter the ear. This helps equalize pressure and prevent pain or discomfort in the ear.
Impaired function of the pharyngotubal muscle can lead to a variety of problems, including ear pain, tinnitus, balance problems, and even deafness. The good news is that this muscle can be trained to help improve its function.
In conclusion, the pharyngotubal muscle plays an important role in swallowing, breathing, and pressure balance in the ear. Impaired function can lead to a variety of problems, but training the muscle can help improve its function and prevent future problems.
