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 ...
Micrograph of a cystic Walthard cell rest (lower right of image) within the connective tissue of a fallopian tube (tubal epithelium – upper left of image). H&E stain . Walthard cell rests , sometimes called Walthard cell nests , are a benign cluster of epithelial cells most commonly found in the connective tissue of the fallopian tubes , but ...
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 ...
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.

The more proximal portions of the ductal system are lined by transitional epithelium and may be lined by columnar epithelium before arborization into glandular secretory elements. [ 5 ] These glands lie on the perineal membrane and beneath the bulbospongiosus muscle at the tail end of the vestibular bulb deep to the posterior labia majora .
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]
