Synonym: Arcus palatinus
English:
Definition[Bearbeiten]
The palatine arches are two arch-shaped soft tissue folds that extend from the lateral edge of the soft palate.
Anatomy[Bearbeiten]
A distinction is made between
- anterior palatoglossal arch (Arcus palatoglossus) and
- posterior palatal arch (Arcus palatopharyngeus)
The anterior palatal arch is formed by the palatoglossus muscle and runs from the soft palate to the lateral base of the tongue.
The posterior palatal arch is formed by the palatopharyngeus muscle and runs from the soft palate to the pharynx (throat).
The palatine tonsils (tonsillae palatinae) lie between the palatine arches on both sides. An injury to the palatine arch can lead to open nasal passages due to impaired phonation.
