the first one is the singular, and the second is the plural
Epithelium is the singular form; the plural forms are epitheliums or epithelia, both are accepted.
The term for epithelium with more than one layer is stratified epithelium.
Epithelia are tissues consisting of closely apposed cells without intervening intercellular substances. Epithelia are avascular, but all epithelia "grow" on an underlying layer of vascular connective tissue. The connective tissue and the epithelium are separated by a basement membrane. Epithelium covers all free surfaces of the body. Epithelium also lines the large internal body cavities, where it is termed mesothelium.
stratified epithelia
Transitional epithelium contains cells that are flattened and cells that are cuboidal; hence the name "transitional". Stratified squamous is different from transitional epithelium since the shape of the individual cell is more hexagonal and contains flattened cells. Transitional epithelium have the capacity to stretch and flatten.

Transitional epithelium have the capacity to stretch and flatten.
Stratified squamous epithelia are named based on the characteristics of the uppermost layer of cells. If the top layer is composed of squamous (flat) cells, the epithelium is referred to as "stratified squamous epithelium." This naming convention helps to identify the type of epithelium based on its surface features and function.
Yes, epithelium consists of closely packed cells that form the protective covering of internal and external surfaces of the body. These cells are tightly packed together with minimal extracellular matrix between them.
simple squamous epithelium
Pseudostratified ciliated columnar epithelium lines most of the respiratory tract. This type of epithelium helps to trap foreign particles and move them out of the respiratory system with the help of cilia.
Epithelia cells are the first cell type that differentiate in the embryo during the 8 cell stage. Epithelia are tissues that are formed by epithelial cells. These specialized cells are differ from others by the nature of avascular, sensory, gliding surface layer, tight barrier and differs from endothelial cells. They form the major cavities of the body. These cells form lungs, kidney, kidney, pancreas and so on. Epithelia act as sensory receptors, hence they form taste buds, nose, ear, female reproductive organs and so on.
as sensory epithelia. These epithelia are found in specific sensory organs such as the olfactory epithelium for smell, the taste buds for taste, the retina for sight, the macula and cristae in the inner ear for equilibrium, and the cochlea in the inner ear for hearing. They are highly specialized to detect and transmit sensory information to the brain.
