The fauces, isthmus of fauces, or the oropharyngeal isthmus is the opening at the back of the mouth into the throat.[1] It is a narrow passage between the velum and the base of the tongue.[2]
The fauces is a part of the
oral cavity as a subdivision, bounded superiorly by the soft palate, laterally by the palatoglossal and palatopharyngeal arches, and inferiorly by the tongue. The arches form the pillars of the fauces. The anterior pillar is the palatoglossal arch formed of the palatoglossus muscle. The posterior pillar is the palatopharyngeal arch formed of the palatopharyngeus muscle. Between these two arches on the lateral walls of the oropharynx is the tonsillar fossa which is the location of the palatine tonsil.[3]
The arches are also known together as the palatine arches.
Each arch runs downwards, laterally and forwards, from the soft palate to the side of the tongue. The approximation of the arches due to the contraction of the palatoglossal muscles constricts the fauces, and is essential to swallowing.
Faucitis
Inflammation of the fauces, known as faucitis, is seen in animals. In cats, faucitis is usually a secondary disease to
depomedrol) or chemotherapy (e.g. chlorambucil
).
