Ben Davis April 21, What makes transitional epithelium different from other epithelial tissue cells? How is transitional epithelium unique compared with other epithelial types? How does the structural difference of transitional epithelium reflect its function in the body? How does this unique characteristic of transitional epithelium reflect its function in the body?

What is a unique feature of transitional epithelium? What is an example of transitional epithelium? Where are transitional epithelium found? What does stratified cuboidal epithelium look like? How many layers does stratified cuboidal epithelium have? What is the main function of stratified columnar epithelium?

What are the functions of stratified columnar epithelium? What are the characteristics of stratified squamous epithelium? It is sometimes called the urothelium since it is almost exclusively found in the bladder, ureters, and urethra. Privacy Policy. Skip to main content. Organization at the Tissue Level. Search for:. Epithelial Tissue. Characteristics of Epithelial Tissue The human body consists of four types of tissue: epithelial, connective, muscular, and nervous.

Learning Objectives Describe the primary functions and characteristics of epithelial tissue. Key Takeaways Key Points Epithelial tissue is composed of cells laid together in sheets with the cells tightly connected to one another. Epithelial layers are avascular, but innervated.

Epithelial cells have two surfaces that differ in both structure and function. Glands, such as exocrine and endocrine, are composed of epithelial tissue and classified based on how their secretions are released. Key Terms epithelium : A membranous tissue composed of one or more layers of cells that form the covering of most internal and external surfaces of the body and its organs.

Types of Epithelial Tissue Epithelial tissue is classified by cell shape and the number of cell layers. Learning Objectives Classify epithelial tissue by cell shape and layers. Key Takeaways Key Points There are three principal cell shapes associated with epithelial cells: squamous epithelium, cuboidal epithelium, and columnar epithelium.

There are three ways of describing the layering of epithelium: simple, stratified, and pseudostratified. Pseudostratified epithelium possesses fine hair-like extensions called cilia and unicellular glands called goblet cells that secrete mucus.

This epithelium is described as ciliated pseudostratified epithelium. Stratified epithelium differs from simple epithelium in that it is multilayered. It is therefore found where body linings have to withstand mechanical or chemical insult. In keratinized epithelia, the most apical layers exterior of cells are dead and and contain a tough, resistant protein called keratin.

An example of this is found in mammalian skin that makes the epithelium waterproof. Transitional epithelia are found in tissues such as the urinary bladder where there is a change in the shape of the cell due to stretching. Key Terms simple columnar : A columnar epithelium that is uni-layered.

Keratinized : To produce or become like keratin. Licenses and Attributions. CC licensed content, Shared previously. Simple squamous epithelium.
