Transitional epithelium is a type of tissue that changes shape in response to stretching (stretchable epithelium). The transitional epithelium usually appears cuboidal when relaxed and squamous when stretched. [1] This tissue consists of multiple layers of epithelial cells which can contract and expand in order to adapt to the degree of ...

Parakeratinized epithelium is sometimes found in the oral mucosa and in the upper regions of the oesophagus. [12] Transitional: Transitional epithelia are found in tissues that stretch, and it can appear to be stratified cuboidal when the tissue is relaxed, or stratified squamous when the organ is distended and the tissue stretches.

Transitional epithelium and transitional carcinoma [6] Cytokeratin 8: Glandular epithelia of the digestive, respiratory and urogenital tracts, both endocrine and exocrine cells, as well as mesothelial cells; Adenocarcinomas originating from those above [6] Cytokeratin 10: Keratinized stratified epithelium
These are located just beneath the fascia and their ducts drain into the vestibular mucosa. These mucoid alkaline secreting glands are arranged as lobules consisting of alveoli lined by cuboidal or columnar epithelium. Their efferent ducts are composed of transitional epithelium, which merges into squamous epithelium as it enters the distal ...
In biology, tissue is an assembly of similar cells and their extracellular matrix from the same embryonic origin that together carry out a specific function. [1] [2] Tissues occupy a biological organizational level between cells and a complete organ.
Pseudostratified columnar epithelium is a type of epithelium that, though comprising only a single layer of cells, has its cell nuclei positioned in a manner suggestive of stratified columnar epithelium. A stratified epithelium rarely occurs as squamous or cuboidal.
