Muscle Compressing the Pharynx, Middle (M. Constrictor Pharyngis Medius, Pna, Bna)

The pharyngeal constrictor muscle, middle (m. constrictor pharyngis medius, pna, bna) is one of the three pharyngeal constrictor muscles. It is located between the superior and inferior constrictor muscles.

The constrictor pharyngeal medius muscle originates from the horn and body of the hyoid bone. Its muscle fibers run backward and upward, covering the pharynx. The constrictor medius muscle attaches to the fascia of the neck.

The function of the constrictor pharyngeal medius muscle is to compress the pharynx during swallowing. It is also involved in the movements of the epiglottis during swallowing and phonation.

The muscles of the esophagus and pharynx are complex formations, which include many muscle fibers that carry out movements and states. The most common muscle, which is important in the functioning of the entire gastrointestinal tract and is directly involved in the processes of breakdown of food and regulation of motility of other abdominal organs, is the constrictor pylori muscle - that is, the sphincter muscle, which originates from the first thoracic branchial arch, intersects with esophagus. Together with a number of neighboring muscles and their fibers, it forms circular folds at the entrance to the esophagus
