Oral Cavity

The oral cavity (lat. Cavum oris) is the space which is limited to the front by the lips, to the top by the hard and soft palate which separates it from the nasal cavity, to the side by the cheeks and to the bottom by the floor of the mouth. To the rear, the oral cavity merges into the middle one, which lies behind the two palatal arches. The palatine tonsil (Tonsilla palatina) lies between the anterior (Arcus palatoglossus) and posterior palate arches (Arcus palatopharyngeus). Together with the almonds (Tonsillae pharyngeae) and the lingual tonsil (Tonsilla lingualis), they form a ring-shaped group, the so-called Waldeyer's pharyngeal ring, named after the anatomist Heinrich Wilhelm Waldeyer. The front opening of the oral cavity is the mouth cleft (Rima oris), the rear one the pharynx or pharyngeal narrowing (Isthmus faucium). The entire oral cavity is lined with a mucous membrane that carries a multi-layered, unkeratinized squamous epithelium. the space between the lips/cheeks and the rows of teeth or, in the case of the edentulous, the projections of the jaw bones protruding into the oral cavity (″Alveolarfortsätze″) is referred to as the oral vestibule. The parotid gland (parotid gland) and the lip and cheek glands lead into the oral vestibule. The space within the dental arches is called the actual oral cavity (lat. Cavum oris proprium). This is where the ducts of the sublingual glands (i.e. under the tongue) and the submandibular glands (i.e. under the jaw) flow out; the tongue also lies here. The most important organs in the oral cavity are the tongue, the teeth and the salivary glands. But also the palate, lips and cheeks are important for speaking, chewing and swallowing.
