The mouth consists of two regions: the vestibule and the oral cavity proper. The vestibule is the area between the teeth, lips and cheeks. [3] The oral cavity is bounded at the sides and in front by the alveolar process (containing the teeth) and at the back by the isthmus of the fauces. Its roof is formed by the hard palate.
The body cavity immediately behind the mouth opening, known as the oral cavity (or cavum oris in Latin), [2] is also the first part of the alimentary canal, which leads to the pharynx and the gullet. In tetrapod vertebrates , the mouth is bounded on the outside by the lips and cheeks — thus the oral cavity is also known as the buccal cavity ...
Oral The side of a tooth adjacent to (or the direction toward) the oral cavity, as opposed to buccal, labial or vestibular, which refer to the side of a tooth adjacent to (or the direction toward) the inside of the cheek, lips or vestibule respectively. Oral includes both palatal and lingual.
Oral and maxillofacial pathology refers to the diseases of the mouth ("oral cavity" or "stoma"), jaws ("maxillae" or "gnath") and related structures such as salivary glands, temporomandibular joints, facial muscles and perioral skin (the skin around the mouth). [1] [2] The mouth is an important organ with many different functions. It is also ...
The oral mucosa is the mucous membrane lining the inside of the mouth. It comprises stratified squamous epithelium, termed "oral epithelium", and an underlying connective tissue termed lamina propria. [1] The oral cavity has sometimes been described as a mirror that reflects the health of the individual. [2]
3D medical illustration explaining the oral digestive system. The mouth is the first part of the upper gastrointestinal tract and is equipped with several structures that begin the first processes of digestion. [3] These include salivary glands, teeth and the tongue. The mouth consists of two regions; the vestibule and the oral cavity proper.
The palate (/ ˈ p æ l ɪ t /) is the roof of the mouth in humans and other mammals.It separates the oral cavity from the nasal cavity. [1] A similar structure is found in crocodilians, but in most other tetrapods, the oral and nasal cavities are not truly separated.
A sagittal (side view) of a human nasal and oral passage. The upper alveolar ridge is located between numbers 4 and 5. The upper alveolar ridge is located between numbers 4 and 5. The alveolar ridge is an area of particular interest in dentistry, as preservation of the ridges results in a higher success rate of therapeutic dental treatments.
