Lip: mucosal surface
The minor salivary glands of the lip, also called labial glands, produce both serous and mucous secretions; their ducts empty into the vestibule of the oral cavity. The epithelium and surface of the inner lip lie above this image. These glands are located in the submucosa near the fibers forming the orbicularis oris muscle. 100x
