Palatopharyngeal Arch[edit]
The palatopharyngeal arch, also known as the posterior pillar of the fauces, is a structure in the human oral cavity. It is one of the two arches that form the fauces, the other being the palatoglossal arch.
Anatomy[edit]
The palatopharyngeal arch is formed by the palatopharyngeus muscle and is covered by a mucous membrane. It extends from the soft palate to the side of the pharynx, forming a vertical fold. This arch is located posterior to the palatine tonsil and the palatoglossal arch.
Function[edit]
The primary function of the palatopharyngeal arch is to assist in the movement of the pharynx during swallowing and speech. The palatopharyngeus muscle helps elevate the pharynx and larynx, facilitating the passage of food and air.
Clinical Significance[edit]
The palatopharyngeal arch is often examined during a physical examination of the throat. Inflammation or swelling of this area can indicate infections such as tonsillitis or pharyngitis.
