Which slide indicates the type of epithelium found in the urinary bladder?

Transitional epithelium
Slide 43. Transitional epithelium — diagnostic for urinary tract. The surface cells are characteristically dome-shaped and puffy.

Is transitional epithelium found in the bladder?

When the urinary bladder fills with urine, the bladder wall stretches to accommodate the increased volume. In the distended bladder, the urothelium reorganizes into two or three layers without any structural damage. Due to this transitional ability of the urothelium, it is also known as the transitional epithelium.

Why is the bladder lined with transitional epithelium?

Unlike the mucosa of other hollow organs, the urinary bladder is lined with transitional epithelial tissue that is able to stretch significantly to accommodate large volumes of urine. The transitional epithelium also provides protection to the underlying tissues from acidic or alkaline urine.

How do you identify transitional epithelium?

Transitional epithelium is a stratified tissue in which the cells are all have a fairly round shape when the organ it lines is not distended (stretched out). The image shows the wall of the urinary bladder in the relaxed state (not distended).

What is a transitional epithelium?

anatomy. : epithelium (as of the urinary bladder) consisting of several layers of cells which become flattened when stretched (as when the bladder is distended)

What is transitional epithelium example?

Transitional epithelium is a type of stratified epithelium. Transitional epithelium lines the organs of the urinary system and is known here as urothelium. The bladder for example has a need for great distension.

Is histology the same as histopathology?

The National Cancer Institute defines histopathology as “the study of diseased cells and tissues using a microscope.”1 Histology is the study of tissues, and pathology is the study of disease. So taken together, histopathology literally means the study of tissues as relates to disease.

Why is histology important?

The study of histology is essential for medical students in multiple ways. It helps students understand the arrangement of cells and tissues in a normal organ system. Moreover, it correlates the structure to function by correlating the differentiation of tissue structure to their specific function.

What is the transitional epithelium?

Where do you find transitional epithelium?

urinary bladder
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.

What is the main function of transitional epithelium?

Function. The transitional epithelium cells stretch readily in order to accommodate fluctuation of volume of the liquid in an organ (the distal part of the urethra becomes non-keratinized stratified squamous epithelium in females; the part that lines the bottom of the tissue is called the basement membrane).

Is the urinary bladder lined by transitional epithelium?

Urinary Bladder The urinary bladder is lined by transitional epithelium, underneath which are thick layers of smooth muscle interwoven in various directions. This image shows a relaxed bladder where the epithelial cells appear cuboidal. In a distended bladder the epithelial cells are stretched and become more squamous.

Why are the cells of the transitional epithelium often binucleate?

Working through Histology slides of the transitional epithelium (urothelium) of the urinary bladder, I noticed that the dome-shaped cells at the top of the transitional epithelium are frequently binucleate. In doing research, I found that the top cells of the transitional epithelium are ‘often binucleate and usually polyploid’ Why is this?

How are the epithelial cells in the bladder stretched?

This image shows a relaxed bladder where the epithelial cells appear cuboidal. In a distended bladder the epithelial cells are stretched and become more squamous.

Where is the transitional epithelium located in the kidney?

Transitional epithelium is characteristic of the urinary mucosa. It is present from the lining of the calyces in the kidney to the urethra, thus forming the mucosal lining of all the post-renal urinary tubes and organs.
