Inner most layer is Cuboidal rest-on underlying connective tissue
Explanation:
Transitional epithelium is a type of stratified epithelium that lines the urinary bladder, ureters, and parts of the urethra. It is characterized by its ability to stretch and recoil without being damaged. The inner most layer of transitional epithelium is cuboidal in shape, and it rests on the underlying connective tissue.
Here is a detailed explanation of the different layers of transitional epithelium:
1. Basement membrane: The basement membrane is a thin layer of extracellular matrix that separates the transitional epithelium from the underlying connective tissue. It provides support and acts as a barrier between the epithelium and the connective tissue.
2. Basal layer: The basal layer is the innermost layer of the transitional epithelium. It consists of cuboidal cells that are closely packed together. These cells are attached to the basement membrane and have a high mitotic activity, allowing for the constant renewal of the epithelium.
3. Intermediate layer: The intermediate layer is located above the basal layer and is composed of several layers of polyhedral cells. These cells have a variable shape and can stretch and change their shape to accommodate the distension of the urinary tract.
4. Superficial layer: The superficial layer is the outermost layer of the transitional epithelium. It consists of large, dome-shaped cells called umbrella cells. These cells are highly specialized and have the ability to flatten and expand when the urinary tract is stretched. The flattened shape of the umbrella cells allows for increased surface area and prevents leakage of urine.
In summary, the innermost layer of transitional epithelium is cuboidal in shape and rests on the underlying connective tissue. This arrangement provides flexibility and allows the epithelium to stretch and recoil without damage.
