Final answer:
The urinary bladder contains transitional epithelium, which can change in thickness and cell shape to accommodate the volume of urine, transitioning from a thicker, cuboidal appearance when empty to thinner and more squamous as it fills.
Step-by-step explanation:
The type of epithelial cell found in the urinary bladder is the transitional epithelium, also known as uroepithelial cells. This unique tissue is specifically designed to cope with the fluctuating volume of urine in the bladder. Transitional epithelia are arranged in a stratified layer and can change in thickness; when the bladder is empty, the tissue appears thicker and when it's full, the cells stretch out and make the lining thinner. In its relaxed form, the apical cells appear cuboidal, but as the bladder distends, they become squamous in shape, allowing the organ to expand.
The type of epithelial cell found in the urinary bladder is transitional epithelium. Transitional or uroepithelial cells are arranged in a stratified layer and have the capability to appear piled up on top of each other in a relaxed, empty bladder. As the urinary bladder fills, the epithelial layer unfolds and expands to accommodate the volume of urine introduced into it.
