What is included in the vestibule of the mouth?
The vestibule – the space between the soft tissue (lips and cheeks), and the teeth and gums. The alveolar arches (bony structures that contain the teeth) surround the mouth cavity at the front and on the sides – overhead are the hard and soft palates and below is the tongue.
Is the buccal mucosa part of the vestibule of the mouth?
The oral vestibule is the area between the cutaneous borders of the lips and the teeth. The lips and the buccal mucosa are the components of the oral vestibule, which plays important roles in oral competence, mastication and speech.
What is a buccal vestibule?
The buccal vestibule is the space external to teeth and gums and internal to lips and cheeks. PPP When the mouth is closed the buccal vestibule and the mouth cavity proper connect via spaces between and behind the teeth. These allow free communication between the two sides of the vestibule.
What mucosal tissue covers the vestibule?
The nasal vestibule is completely lined by squamous epithelium. It is a stratified epithelium composed of basal cells along the basal lamina and several layers of squamous cells, which become progressively flatter toward the luminal surface.
What is the function of the vestibule in the mouth?
Its primary function is to serve as the entrance of the alimentary tract and to initiate the digestive process by salivation and propulsion of the alimentary bolus into the pharynx. It also serves as a secondary respiratory conduit, a site of sound modification for the production of speech, and a chemosensory organ.
Is the tongue part of the oral mucosa?
A number of cranial nerves are involved in sensations in the mouth including trigeminal (V), Facial (VII), glossopharyngeal (IX) and Vagus (X) nerves. The dorsum of the tongue is covered in specialised mucosa. This contains the presence of taste buds allowing taste, and it accounts for around 15% of oral mucosa.
How many vestibule do we have?

What is papillary hyperplasia?
Inflammatory papillary hyperplasia (IPH) is a benign lesion of the oral mucosa which is characterized by the growth of one or more nodular lesions, measuring about 2mm or less. The lesion almost exclusively involves the hard palate, and in rare instances, it also has been seen on the mandible.
What is the difference between the vestibule and the oral cavity?
The oral cavity is arbitrarily divided into two parts: the oral cavity proper which is the region medial to the teeth that houses the tongue and the oral vestibule, which is the space that separates the lips and cheeks from the teeth.
Is the buccal mucosa part of the oral cavity?
In ICD-O-3 and the Summary Stage system, buccal mucosa includes the inner surface of the cheeks but not the inner mucosal surface of the lips. In the AJCC staging system, the inner mucosa of the lips is included with the buccal mucosa in the oral cavity scheme.
How big is the papillae on the dorsal tongue?
It is discerned by elongated, hypertrophic filiform papillae on the dorsal tongue with hair like manifestations due to inadequate desquamation or increased keratinization of the papillae. The papillae usually 1 mm in length, elongate to 12mm. Women and children are predominantly affected.
Is the oral vestibule part of the oral cavity?
The oral cavity can be anatomically divided into the oral vestibule, the space between the teeth and the mucosa of the lips and cheeks, and the oral cavity proper, the space bounded anteriorly and laterally by the teeth and posteriorly by the oropharynx.
How big is the length of the papillae?
The papillae usually 1 mm in length, elongate to 12mm. Women and children are predominantly affected. Heavy smoking, poor oral hygiene, oxidizing mouth washes, candida albicans, certain medications are corroborating factors.
