Palatal Arch Posterior

The palatine arch (Arcus palatinis posterioris) is a structure that is located in the oropharynx and is a connecting segment between the lateral wall of the pharynx and the lower surface of the palate. It is located behind the earlobe and plays an important role in holding food and breathing in the mouth.

Anatomical structure The upper surface of the posterior palatal arch is covered with a gray mucous membrane, and the lower surface is covered with loose connective tissue. Vessels and nerves pass along the lower surface of the arch. Under the mucous layer there are bundles of skeletal muscles that ensure the retention of the pharynx at the bottom. Rear
