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 ...
Cuboidal epithelium has cells whose height and width are approximately the same (cube shaped). Columnar epithelium has cells taller than they are wide (column-shaped). Endothelium refers to cells that line the interior surface of blood vessels and lymphatic vessels , [ 1 ] forming an interface between circulating blood or lymph in the lumen and ...

The ureter is lined by urothelium, a type of transitional epithelium that is capable of responding to stretches in the ureters. The transitional epithelium may appear as a layer of column-shaped cells when relaxed, and of flatter cells when distended. Below the epithelium sits the lamina propria. The lamina propria is made up of loose ...
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 ...
The wall of the navicular fossa is the only part of the urethra that is lined with stratified squamous epithelium (instead of the transitional epithelium that is typical for the urinary tract). [1] During development, the glans of the penis is initially solid but cannulates to give rise to the navicular fossa. [citation needed]
