The fauces is a part of the oropharynx directly behind 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 palatopharyngeal arch (pharyngopalatine arch, posterior pillar of fauces) is larger and projects further toward the middle line than the palatoglossal arch; it runs downward, lateralward, and backward to the side of the pharynx, and is formed by the projection of the palatopharyngeal muscle, covered by mucous membrane.
Upper respiratory system, with the nasopharynx, oropharynx and laryngopharynx labeled at left. The upper portion of the pharynx, the nasopharynx, extends from the base of the skull to the upper surface of the soft palate. [2] It includes the space between the internal nares and the soft palate and lies
Palatal petechiae. Petechiae on the soft palate are mainly associated with streptococcal pharyngitis, [6] and as such it is an uncommon but highly specific finding. [7] 10 to 30 percent of palatal petechiae cases are estimated to be caused by suction, which can be habitual or secondary to fellatio. [8]
The palatine tonsils are located in the isthmus of the fauces, between the palatoglossal arch and the palatopharyngeal arch of the soft palate.. The palatine tonsil is one of the mucosa-associated lymphoid tissues (MALT), located at the entrance to the upper respiratory and gastrointestinal tracts to protect the body from the entry of exogenous material through mucosal sites.

The palatoglossal arch (glossopalatine arch, anterior pillar of fauces) on either side runs downward, lateral (to the side), and forward to the side of the base of the tongue, and is formed by the projection of the glossopalatine muscle with its covering mucous membrane.
The palatovaginal canal (also pharyngeal canal) is a small canal formed between the sphenoidal process of palatine bone, and vaginal process of sphenoid bone. [ 1 ] : 508 It connects the pterygopalatine fossa and [ 1 ] : 370 and nasal cavity .
