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.
Ankyloglossia. Ankyloglossia, also known as tongue-tie, is a congenital anomaly characterised by an abnormally short lingual frenulum; when severe, the tip of the tongue cannot be protruded beyond the lower incisor teeth. [6] There are two generalized classifications of ankyloglossia, anterior and posterior tongue-ties.
Saethre–Chotzen syndrome ( SCS ), also known as acrocephalosyndactyly type III, is a rare congenital disorder associated with craniosynostosis (premature closure of one or more of the sutures between the bones of the skull ). This affects the shape of the head and face, resulting in a cone-shaped head and an asymmetrical face.
Ankyloglossia, also known as tongue-tie, is a congenital oral anomaly that may decrease the mobility of the tongue tip [1] and is caused by an unusually short, thick lingual frenulum, a membrane connecting the underside of the tongue to the floor of the mouth. [2] Ankyloglossia varies in degree of severity from mild cases characterized by ...
Oral mucosa can be divided into three main categories based on function and histology : Lining mucosa, nonkeratinized stratified squamous epithelium, found almost everywhere else in the oral cavity, including the: Alveolar mucosa, the lining between the buccal and labial mucosae. It is a brighter red, smooth, and shiny with many blood vessels ...
Palate. Head and neck. The palate ( / ˈpælɪt /) 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. The palate is divided into two parts, the anterior, bony ...
Mouth. The mouth is the body orifice through which many animals ingest food and vocalize. 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.
The smallmouth bass (Micropterus dolomieu) is a species of freshwater fish in the sunfish family (Centrarchidae) of the order Perciformes. It is the type species of its genus Micropterus (black basses), and is a popular game fish sought by anglers throughout the temperate zones of North America, and has been spread by stocking—as well as illegal introductions—to many cool-water tributaries ...
The shape and dimensions of the proboscis have evolved to give different species a wider and therefore more advantageous diet. There is an allometric scaling relationship between body mass of Lepidoptera and length of proboscis [22] from which an interesting adaptive departure is the unusually long-tongued sphinx moth Xanthopan morganii praedicta .
Dimple. A dimple, also called a gelasin (from Latin gelasinus, from Ancient Greek γελασῖνος (gelasînos) ), [1] and a fovea buccalis, [2] is a small natural indentation in the flesh on a part of the human body, most notably in the cheek. Numerous cultures believe that cheek dimples are a good luck charm that entices people who ...
