The myth of the tongue map: that 1 tastes bitter, 2 tastes sour, 3 tastes salty, and 4 tastes sweet. The tongue map or taste map is a common misconception that different sections of the tongue are exclusively responsible for different basic tastes. It is illustrated with a schematic map of the tongue, with certain parts of the tongue labeled ...
The cheeks are referred to as the buccal region. The ears are referred to as the auricle or otic region. The nose is referred to as the nasal region. The mouth is referred to as the oral region. The chin is referred to as the mental region. The neck is referred to as the cervical region. The trunk of the body contains, from superior to inferior,
Lingual papillae, particularly filiform papillae, are thought to increase the surface area of the tongue and to increase the area of contact and friction between the tongue and food. [2] This may increase the tongue's ability to manipulate a bolus of food, and also to position food between the teeth during mastication (chewing) and swallowing.
Anatomy of the mouth. Floor of the mouth with lingual frenum and sublingual fold. 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 tongue is an important accessory organ in the digestive system. The tongue is used for crushing food against the hard palate, during mastication and manipulation of food for softening prior to swallowing. The epithelium on the tongue's upper, or dorsal surface is keratinised. Consequently, the tongue can grind against the hard palate ...
The thin strip of tissue that runs vertically from the floor of the mouth to the undersurface of the tongue is called the lingual frenulum. It tends to limit the movement of the tongue, and in some people, it is so short that it actually interferes with speaking. A hump of tissue near the base of the tongue houses a series of saliva gland ducts.
The taste buds on the tongue sit on raised protrusions of the tongue surface called papillae. There are four types of lingual papillae; all except one contain taste buds: Fungiform papillae - as the name suggests, these are slightly mushroom-shaped if looked at in longitudinal section. These are present mostly at the dorsal surface of the ...
Typically, regions such as the cheeks, lips, and parts of the hard palate contain submucosa (a layer of loose fatty or glandular connective tissue containing the major blood vessels and nerves supplying the mucosa). The submucosa's composition determines the flexibility of the attachment of oral mucosa to the underlying structures.
