Epithelia: meaning, definitions and examples
๐ฆ
epithelia
[ หepษชหฮธiหliษ ]
biological tissue
Epithelia refer to layers of cells that cover the body's surfaces, both inside and out, as well as lining cavities and organs. This type of tissue plays numerous roles, including protection, secretion, and absorption. Epithelial tissue is distinguished by its cells being closely packed together, with minimal extracellular matrix. It's classified based on cell shape and the number of layers, which affects its specific functions. Proper functioning of epithelia is essential for overall health, and dysfunction can lead to various diseases.
Synonyms
cellular lining, epithelial tissue, protective layer
Examples of usage
- The epithelia protect underlying tissues.
- Epithelia play a key role in absorption.
- The respiratory epithelia trap dust and allergens.
- Epithelia are involved in secretion of mucus.

Word origin
The term 'epithelia' is derived from the Greek words 'epi' meaning 'upon' or 'above', and 'thele' meaning 'nipple' or 'suture'. Historically, the term was first used in medical Latin in the early 19th century to describe the tissue that covers both the external surface of the body and the lining of bodily cavities. Throughout history, the understanding of epithelial layers has evolved, particularly with advances in microscopy, leading to more detailed classifications based on structure and function. The study of epithelia has been fundamental in the field of histology and pathology, impacting our understanding of organ function and disease.
