What type of tissue makes up the urinary bladder?

It is a special type of lining that stretches as the bladder fills up. It stops the urine being absorbed back into your body. The lining is called transitional epithelium. The second layer is a thin layer of connective tissue called the lamina propria.
A.

What are the four layers of the 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.
  • What type of muscle is the bladder?

    Detrusor muscle. The detrusor muscle is a layer of the urinary bladder wall made of smooth muscle fibers arranged in spiral, longitudinal, and circular bundles.
  • What is the name for painful or difficult urination?

    In medicine, specifically urology, dysuria refers to painful urination. Difficult urination is also sometimes, but rarely, described as dysuria. It is one of a constellation of irritative bladder symptoms (also sometimes referred to as lower urinary tract symptoms), which includes nocturia and urinary frequency.
  • What is the urine made up of?

    The system produces urine by a process of filtration, reabsorption, and tubular secretion. The kidneys extract the soluble wastes from the bloodstream, as well as excess water, sugars, and a variety of other compounds. The resulting urine contains high concentrations of urea and other substances, including toxins.
B.

What are the three layers of the ureter wall?

The wall of the ureter consists of three layers. The outer layer, the fibrous coat, is a supporting layer of fibrous connective tissue. The middle layer, the muscular coat, consists of the inner circular and outer longitudinal smooth muscle. The main function of this layer is peristalsis: to propel the urine.
  • What are the three regions of the male urethra?

    The three regions / sections of the male urethra are:
    • Prostatic Urethra. The prostatic urethra begins at the neck of the bladder and includes all of the section that passes through the prostrate gland.
    • Membranous Urethra. The membranous urethra is the shortest and narrowest part of the male urethra.
    • Spongy Urethra.
  • Which muscle forms the walls of the bladder?

    The detrusor muscle is a layer of the urinary bladder wall made of smooth muscle fibers arranged in spiral, longitudinal, and circular bundles.
  • What is included in the formation of urine?

    The kidneys filter unwanted substances from the blood and produce urine to excrete them. There are three main steps of urine formation: glomerular filtration, reabsorption, and secretion. These processes ensure that only waste and excess water are removed from the body.
C.

What tissues are found in the bladder?

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 many ml of urine does the bladder hold?

    "Although the urinary bladder may hold as much as 600 ml of urine, the desire to urinate is usually experienced when it contains about 150 ml."
  • What kind of cells are in the bladder?

    The wall of the urinary bladder consists of four layers. The inner layer, or mucous coat, is composed of epithelial cells. The second layer, or submucous layer, is made up of connective tissue and contains many elastic fibers.
  • How much water does your bladder hold?

    A healthy bladder can hold one and a half to two cups (300-400mls) of urine during the day and about four cups (800mls) at night. It is normal to pass urine five or six times a day if you drink between 6-8 glasses of fluid.
