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 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 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 .
The pharyngeal muscles are a group of muscles that form the pharynx, which is posterior to the oral cavity, determining the shape of its lumen, and affecting its sound properties as the primary resonating cavity. The pharyngeal muscles (involuntary skeletal) push food into the esophagus.
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.
A few fibers of palatopharyngeus muscle sweep backward under cover of the Passavant's ridge and form a U-shaped sling of palatopharyngeal sphincter. When the soft palate is elevated it comes in contact with ridge, the two together closing pharyngeal isthmus between nasopharynx and oropharynx. [2]
Some sources state that the palatoglossus is innervated by fibers from the cranial part of the accessory nerve (CN XI) that travel via the pharyngeal plexus. [2]Other sources state that the palatoglossus is not innervated by XI hitchhiking on X, but rather it is innervated by IX via the pharyngeal plexus formed from IX and X. [3]
