Tongue01:01

Tongue

The human tongue is a fascinating and complex organ, responsible for various essential functions such as swallowing, speech, and taste. It is also subject to various conditions and diseases. In this article, we delve into the anatomy of the tongue, its roles, and some common conditions that can affect it.
Anatomical Position in the Oral Cavity
The tongue is located within the oral cavity, also known as the mouth. It is attached to the floor of the mouth by a fold of mucous membrane called the...
The Tongue and Taste Buds00:49

The Tongue and Taste Buds

The surface of the tongue is covered with various small bumps called papillae, which either distribute what has been ingested (filiform papillae) or contain the sensory taste (or gustatory) receptor cells (fungiform, circumvallate, and foliate papillae). Embedded within each taste-related papilla are the taste buds—clusters of 30 to 100 gustatory receptor cells.
Deglutition01:25

Deglutition

Swallowing, otherwise known as deglutition, facilitates the transport of food from the mouth to the stomach. It is a multifaceted process that involves both the tongue and the muscles of the throat and esophagus. Saliva and mucus aid in this process, which takes approximately 4 to 8 seconds for semi-solid or solid food and around 1 second for liquids or very soft food.
Swallowing can be divided into three stages: the voluntary phase, the pharyngeal phase, and the esophageal phase. Although the...
Taste Buds and Receptors01:20

Taste Buds and Receptors

Gustation, or the sense of taste, is intrinsically linked to the anatomical structures located on the tongue. This organ's surface, along with the entirety of the oral cavity, is adorned with stratified squamous epithelium. Evident on the tongue are elevated structures known as papillae (singular = papilla), which house the mechanisms for the transduction of gustatory stimuli. Four distinct types of papillae exist, each identified by their unique morphological attributes: the circumvallate,...
Conditioned Taste Aversion01:14

Conditioned Taste Aversion

Conditioned taste aversion, also known as sauce béarnaise syndrome, is a phenomenon in which an individual develops an aversion to a certain food taste following a negative experience, typically illness. This form of aversion is a type of classical conditioning in which the taste of the food (conditioned stimulus, CS) is associated with the experience of illness (unconditioned stimulus, UCS).
A notable characteristic of conditioned taste aversion is that it often requires only a single exposure...
Assessment of the Mouth01:26

Assessment of the Mouth

A thorough mouth assessment, including inspection and palpation of the lips, gums, tongue, tonsils, uvula, and pharynx, is crucial in detecting potential health issues. Diseases ranging from oral cancer to systemic conditions like diabetes could be identified early through careful oral examination. This article provides a detailed guide on conducting a comprehensive mouth assessment.
Mouth Inspection
The inspection begins with visually examining the mouth for symmetry, color, and size.

Area of Science:

  • Food Science
  • Bioinformatics
  • Information Science

Background:

  • European Food Information Resource (EuroFIR) network aims to consolidate validated food composition data (FCD) from 27 European countries.
  • Challenges in data harmonization include diverse languages, food cultures, and lack of standardized food classification (only 25% of databases used it in 2005).

Purpose of the Study:

  • To implement a standardized system for describing and linking foods within European food composition databases (FCDBs).
  • To overcome language and cultural barriers for improved data comparability and integration into the EuroFIR network.

Main Methods:

  • Utilized the LanguaL thesaurus for systematic food indexing and description.
  • Developed and implemented LanguaL Food Product Indexer software.
  • Conducted short food indexing courses for FCD compilers across participating countries.
  • Facilitated feedback between the LanguaL Technical Committee and FCD compilers for thesaurus improvement.

Main Results:

  • Over 26,000 foods in national databases and 2360 foods in specialized datasets were indexed using LanguaL.
  • Standardized descriptions enabled linking of foods across national databases and specialized datasets.
  • Improved food indexing skills among FCD compilers.
  • LanguaL thesaurus enriched with new descriptors and translations based on compiler expertise.

Conclusions:

  • Standardized food description via the LanguaL thesaurus successfully linked and enabled comparison of foods across European borders and languages.
  • Both the EuroFIR network and national FCDB compilers benefited from enhanced data harmonization and interoperability.
  • Collaborative efforts improved both the LanguaL thesaurus and the FCD compilers' expertise.
