What are Palatoglossal Arches?
The right and left palatoglossus muscles create ridges in the lateral pharyngeal wall, referred to as the palatoglossal arches (anterior faucial pillars). These pillars separate the oral cavity and the oropharynx — the muscle functions as an antagonist to the levator veli palatini muscle.

What is Arch in throat called?
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.
What is the Salpingopharyngeus?
The salpingopharyngeus is a muscle of the head and neck, and one of the inner longitudinal muscles of the pharynx. The paired slender muscles create vertical ridges of mucous membrane in the posterior pharyngeal wall descending from the medial ends of the Eustachian tubes to the called the salpingopharyngeal folds.
What lies between palatopharyngeal folds and Palatoglossal folds?
Palatine tonsillar bed (N60) – fossa between palatoglossal and palatopharyngeal arches.
