What is the composition of the urinary bladder?

Urinary Bladder. The wall of the urinary bladder has four layers. From the inside towards the outside they are: mucosa, submucosa, muscularis, and serosa or adventitia. The outside layer is either serosa or adventitia, depending on location–see your textbook for an explanation.

What type of epithelial tissue is found in the urinary bladder quizlet?

What cell line is the bladder?

The bladder wall is made of many layers, including: Urothelium or transitional epithelium. This is the layer of cells that lines the inside of the kidneys, ureters, bladder, and urethra. Cells in this layer are called urothelial cells or transitional cells.

What is the function of the urinary bladder?

The urinary bladder is a muscular sac in the pelvis, just above and behind the pubic bone. When empty, the bladder is about the size and shape of a pear. Urine is made in the kidneys and travels down two tubes called ureters to the bladder. The bladder stores urine, allowing urination to be infrequent and controlled.

What is the urinary bladder composed of?

It is composed of connective tissue with elastic fibers. The next layer is the muscularis, which is composed of smooth muscle. The smooth muscle fibers are interwoven in all directions and, collectively, these are called the detrusor muscle.

What triggers the urinary reflex?

When the bladder is full of urine, stretch receptors in the bladder wall trigger the micturition reflex. The detrusor muscle that surrounds the bladder contracts. The internal urethral sphincter relaxes, allowing for urine to pass out of the bladder into the urethra. Both of these reactions are involuntary.
