n. pl. ep·i·the·li·a (-lē-ə) or ep·i·the·li·ums
Membranous tissue composed of one or more layers of cells separated by very little intercellular substance and forming the covering of most internal and external surfaces of the body and its organs.

[New Latin epithēlium : epi- + Greek thēlē, nipple; see dhē(i)- in Indo-European roots.]

(ˌɛpɪˈθiːlɪəm)

(Anatomy) an animal tissue consisting of one or more layers of closely packed cells covering the external and internal surfaces of the body. The cells vary in structure according to their function, which may be protective, secretory, or absorptive
[C18: New Latin, from epi- + Greek thēlē nipple]

ep•i•the•li•um

(ˌɛp əˈθi li əm)

n., pl. -li•ums, -li•a (-li ə)
any tissue layer covering body surfaces or lining the internal surfaces of body cavities, tubes, and hollow organs.

ep·i·the·li·um

(ĕp′ə-thē′lē-əm)
The thin, protective layer of cells that covers most of the outer surface of an animal body and lines the inner surface of many body parts. In vertebrate animals, the outer layer of the skin, called the epidermis, is composed of epithelium.

epithelium

1. A type of animal tissue that covers inner and outer surfaces.
2. The layer of cells covering the body’s surface and lining the alimentary canal and respiratory and urinary tracts.
