AI Article Synopsis
- The study focused on the palatopharyngeal muscle's characteristics, looking at where it starts and ends, and how it relates to nearby muscles.
- Researchers found that this muscle usually originates from both the oral and nasal sides of the soft palate and can connect to various areas in the pharynx.
- The findings indicate that the palatopharyngeal muscle has significant connections with other muscles involved in palate and throat movement, affecting swallowing and speech.
Article Abstract
In an effort to clarify the morphologic characteristics of the palatopharyngeal muscle, we examined its origin, insertion, and positional relationship with other muscles. We found that the origin of the palatopharyngeal muscle was both the oral and the nasal side of the soft palate; it was also attached to both the palatal aponeurosis and the soft palate median. However, in some cases the muscle originated on the nasal side was lacked. When the palatopharyngeal muscle originated from both the oral and the nasal side, it traveled through its insertion via the levator muscle of the palatine velum. This insertion was seen in a wide area and could be divided into three parts: the pharynx anterior, central, and posterior walls. In the central pharyngeal wall, insertion into the pharyngeal aponeurosis, inferior constrictor pharyngeal muscle, and esophagus were observed. The present results suggest that the palatopharyngeal muscle has a close positional relationship with the levator and tensor muscles of the palatine velum, the pharyngeal constrictor muscles, and the esophagus.
