The Anatomy of the Oral Cavity
The Oropharyngeal Isthmus
The oropharyngeal isthmus, also known as the isthmus of fauces, is a narrow passageway located at the back of the mouth. It connects the oral cavity to the oropharynx, which is the middle part of the throat.
The Boundaries of the Oral Cavity
The oral cavity is bounded by the following structures:
- Anteriorly: The lips and teeth
- Laterally: The cheeks and alveolar arches
- Posteriorly: The oropharyngeal isthmus
- Superiorly: The palate and hard palate
- Inferiorly: The tongue and floor of the mouth
Conclusion
The oral cavity is a complex and vital structure that plays a role in speaking, eating, and digestion. The oropharyngeal isthmus is a key part of the oral cavity, and its constriction helps to prevent food and other objects from entering the airway.
