A brief overview of Urinary Bladder
Cancer
Urinary bladder cancer is a type of cancer that starts in the urinary bladder. The urinary bladder is a hollow organ in the lower part of the abdomen that stores urine. The cancer may start in the cells that line the inside of the bladder or in the muscle layer of the bladder.
What is the Urinary Bladder?
The urinary bladder is a hollow, muscular organ in the lower abdomen that stores urine until it is expelled from the body through the urethra. The urinary bladder is triangular in shape and its base is located near the pubic bone. The bladder’s two ureteric orifices, which allow urine to flow into and out of the bladder, are located on its superior surface. The trigone, a triangular area at the base of the bladder, is the most sensitive area of the bladder. The bladder is surrounded by a layer of connective tissue and its outer surface is lined with a layer of transitional epithelium, which can stretch to accommodate increasing volumes of urine.
Parts and Structure of Urinary Bladder
The urinary bladder is a hollow, muscular organ in the lower abdomen that stores urine until it is expelled from the body. The bladder is lined with a mucous membrane, and has two openings: one for the urethra, which carries urine from the bladder to the outside of the body, and one for the vagina in women. The bladder is a triangular-shaped organ that is about 8 inches long and 4 inches wide. It is supported by ligaments and muscles, including the pelvic floor muscles and the detrusor muscle. The bladder is made up of three layers: the serous, the muscular, and the mucous. The serous layer is the thin outermost layer, the muscular layer is the thick middle layer, and the mucous layer is the innermost layer. The serous layer is composed of two layers of tissue: the visceral layer, which covers the bladder, and the parietal layer, which lines the inside of the bladder. The muscular layer is composed of smooth muscle tissue and is responsible for the bladder’s ability to contract and expel urine. The mucous layer is composed of transitional epithelium, which is a type of epithelium that is able to stretch and expand. This layer helps to protect the bladder from urine and other irritants.
Stone in Urinary Bladder
A stone in the urinary bladder is a solid mass that forms in the bladder, usually as a result of minerals crystallizing in the urine. Stones can cause pain and difficulty urinating.

The article discusses how the increasing use of technology is changing the way we learn and impacting students’ abilities to think critically. It cites research that shows that students who use laptops in class are more likely to cheat and that those who use smartphones are more likely to be distracted. The article also discusses the positive aspects of technology-mediated learning, such as its ability to help students learn more efficiently.
