The tongue is a muscular organ in the mouth of a typical tetrapod. It manipulates food for chewing and swallowing as part of the digestive process, and is the primary organ of taste. The tongue's upper surface (dorsum) is covered by taste buds housed in numerous lingual papillae. It is sensitive and kept moist by saliva and is richly supplied ...
In human anatomy, the mouth is the first portion of the alimentary canal that receives food and produces saliva. [2] The oral mucosa is the mucous membrane epithelium lining the inside of the mouth. In addition to its primary role as the beginning of the digestive system, the mouth also plays a significant role in communication.
Human digestive system. The human digestive system consists of the gastrointestinal tract plus the accessory organs of digestion (the tongue, salivary glands, pancreas, liver, and gallbladder ). Digestion involves the breakdown of food into smaller and smaller components, until they can be absorbed and assimilated into the body.
Taste bud. Taste buds are clusters of taste receptor cells, which are also known as gustatory cells. [1] The taste receptors are located around the small structures known as papillae found on the upper surface of the tongue, soft palate, upper esophagus, the cheek, and epiglottis. These structures are involved in detecting the five elements of ...

Human anatomy is the study of the shape and form of the human body. The human body has four limbs (two arms and two legs), a head and a neck, which connect to the torso. The body's shape is determined by a strong skeleton made of bone and cartilage, surrounded by fat ( adipose tissue ), muscle, connective tissue, organs, and other structures.
Lingual papillae ( sg.: papilla) are small structures on the upper surface of the tongue that give it its characteristic rough texture. The four types of papillae on the human tongue have different structures and are accordingly classified as circumvallate (or vallate), fungiform, filiform, and foliate. All except the filiform papillae are ...
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 ...
Lingual nerve. Distribution of the maxillary and mandibular nerves, and the submaxillary ganglion. The mouth cavity. The apex of the tongue is turned upward, and on the right side a superficial dissection of its under surface has been made. The lingual nerve carries sensory innervation from the anterior two-thirds of the tongue.
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 for each taste. Although taught in some schools, this is incorrect; all taste sensations come from all ...
