Epithelium: meaning, definitions and examples
๐งฌ
epithelium
[ หepษชหฮธiหliษm ]
biological tissue
Epithelium refers to a type of tissue found in animals that forms a protective layer over body surfaces and lines cavities and organs. It consists of one or more layers of cells and plays crucial roles in absorption, secretion, and sensation. Epithelial tissue can be classified into various types based on the shape of its cells and the number of layers present, including simple and stratified epithelium, cuboidal and columnar epithelium. This tissue is essential for proper functioning of many organs, such as the skin, respiratory tract, and digestive system.
Synonyms
Examples of usage
- The skin is primarily made up of epithelial tissue.
- Epithelial cells line the surfaces of organs and blood vessels.
- The respiratory epithelium helps in the filtration of air.
- Epithelial layers are critical in nutrient absorption in the intestines.

Etymology
The term 'epithelium' originates from the combination of Greek words 'epi', meaning 'upon', and 'thelium', meaning 'nipple' (derived from 'thฤlos'). The concept emerged in the early 19th century as scientists began to classify various body tissues. Epithelium was identified as a distinct tissue type due to its unique properties and functions. Initially, it appeared in the context of anatomy and biology, emphasizing its role in covering body surfaces and forming protective barriers. Over time, as the study of histology advanced, the understanding of epithelial tissue evolved, leading to its detailed classifications based on cell shape and arrangement. Today, epithelium is recognized as a fundamental component of multicellular organisms, with significant implications in health, disease, and medical research.
