The Urinary Bladder Functions of the Bladder. Temporary store of urine – The bladder is a hollow organ. The walls are very distensible, with a folded internal lining (known as rugae), this allows it to hold up to 600ml. Assists in the expulsion of urine – During voiding, the musculature of the bladder contracts, and the sphincters relax.

Bladder (Urinary), Anatomy, Location, Parts and Pictures The urinary bladder is a hollow muscular organ located in the lesser pelvis when empty. It serves as a reservoir for urine and can stretch considerably to store close to a maximum of 500 milliliters of urine.The average full bladder that is not overly distended contains about 350 milliliters of urine.he urinary bladder is a hollow muscular organ located in the lesser pelvis when empty.

- The wall of the bladder has 4 main layers. 1  The innermost lining is made up of cells called urothelial or transitional cells, so this layer is called the urothelium or transitional epithelium. 2  Beneath the urothelium is a thin layer of connective tissue, blood vessels, and nerves, which is called the lamina propria.he wall of the bladder has 4 main layers. 1  The innermost lining is made up of cells called urothelial or transitional cells, so this layer is called the urothelium or transitional epithelium. 2  Beneath the urothelium is a thin layer of connective tissue, blood vessels, and nerves, which is called the lamina propria.

- The wall of the Urinary Bladder consists of three layers: 1  The Mucosa layer. 2  The Detrusor Muscle itself made up by three layers. 3  The Adventitia and the visceral peritoneum.hen the urinary bladder is stretched the parasympathetic nervous system is signaled to contract the detrusor muscle and the urine is squeezed out through the urethra canal. For this to work both the autonomically controlled sphincter muscle and the voluntarily controlled sphincter muscle must be relaxed.

The Urinary Bladder The bladder is an organ of the urinary system, situated anteriorly in the pelvic cavity. It is hollow, highly distensible, and rounded in shape. The main function of the bladder is the collection, temporary storage, and expulsion of urine.

Urethral sphincters The internal sphincter muscle of urethra: located at the bladder's inferior end and the urethra's proximal end at the junction of the urethra with the urinary bladder. The internal sphincter is a continuation of the detrusor muscle and is made of smooth muscle, therefore it is under involuntary or autonomic control.

- The bladder, also known as the urinary bladder, is an expandable muscular sac that stores urine before it is excreted out of the body through the urethra. It is located in the lower abdominal area near the pelvic bones.Read More.he bladder, like the stomach, is an expandable saclike organ that contracts when it is empty. The inner lining of the bladder tucks into the folds and expands out to accommodate liquid. When empty, the bladder’s muscle wall becomes thicker and the entire bladder becomes firm.

- 1 The primary receptors in the bladder neck are alpha-adrenergic. 2  Sympathetic stimulation of these alpha receptors, via fibers in the hypogastric nerve, contributes to urinary continence. 3  The external sphincter is histologically different from the detrusor and internal sphincter. 4  It is striated muscle.

urinary bladder urinary bladder. The urinary bladder is a temporary storage reservoir for urine. It is located in the pelvic cavity (see pelvis), posterior to the symphysis pubis, and below the parietal peritoneum. The size and shape of the urinary bladder varies with the amount of urine it contains and with pressure it receives from surrounding organs.

- The pelvic floor is a group of muscles that supports the bladder and bowel and helps maintain continence. Sphincter muscles help control the opening and closing of the urethra, which leads from the bladder and carries urine out of the body.

Urinary System Anatomy The urinary bladder is located along the body’s midline at the inferior end of the pelvis. Urine entering the urinary bladder from the ureters slowly fills the hollow space of the bladder and stretches its elastic walls. The walls of the bladder allow it to stretch to hold anywhere from 600 to 800 milliliters of urine.he kidneys filter metabolic wastes, excess ions, and chemicals from the blood to form urine. Ureters. The ureters are a pair of tubes that carry urine from the kidneys to the urinary bladder. The ureters are about 10 to 12 inches long and run on the left and right sides of the body parallel to the vertebral column.

urinary bladder Contraction of this muscle expels urine from the bladder. On the superior surface, the outer layer of the bladder wall is parietal peritoneum. In all other regions, the outer layer is fibrous connective tissue. There is a triangular area, called the trigone, formed by three openings in the floor of the urinary bladder.he inner lining of the urinary bladder is a mucous membrane of transitional epithelium that is continuous with that in the ureters. When the bladder is empty, the mucosa has numerous folds called rugae. The rugae and transitional epithelium allow the bladder to expand as it fills.

Urinary Tract Cytology The urinary tract is composed of the kidneys, the ureters, urinary bladder and the urethra. The basal portion of the urinary bladder contains the trigone, a triangular area with the apex directed forward. The urethra leaves the bladder at the apex of the trigone. The female urethra has a short-course opening into the vestibule behind the clitoris.

URINARY BLADDER ANATOMY The neck of the bladder refers to the area encompassing the urethral opening. Four distinct layers create the wall of the urinary bladder. The inner layer is known as the mucosa layer, and this layer is created by transitional epithelium which gradually thins as the bladder distends, creating thinner walls.

Detrusor muscle The detrusor urinae muscle, also detrusor muscle, muscularis propria of the urinary bladder and (less precise) muscularis propria, is smooth muscle found in the wall of the bladder. The detrusor muscle remains relaxed to allow the bladder to store urine, and contracts during urination to release urine.

Urinary Bladder A small funnel forms at the inferior end of the urinary bladder leading into the urethra, the tube that carries urine out of the body during urination. The urinary bladder is made of several distinct tissue layers: The innermost layer of the bladder is the mucosa layer that lines the hollow lumen. 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.

Urethra In females the urethra is about 4 cm long. It passes forward from the bladder, descends below the symphysis pubis, and empties into the labia minor. Its opening is located above the vaginal opening and about 2.5 cm below the clitoris.... Click to read more below. The urethra is a tube that conveys urine from the urinary bladder to the outside of the body. Its wall is lined with mucous membranes and contains a relatively thick layer of smooth muscle tissue. It also contains numerous mucous glands, called urethral glands that secrete mucus into the urethral canal.

Structure of Male Urethra About. The urethra is the tubular part of the urinary system that carries the urine from the urinary bladder to the exterior of the body. It is made up of fibrous tissue and muscle, and is lined by mucus membrane. The urinary system functions to remove waste material from the body.rostatic urethra: The prostatic urethra is that part of the urethra that passes through the prostate. Features of the prostatic urethra are listed below: The prostatic urethra is around 2.5 cm long and extends from the base of the bladder or bladder neck to the membranous urethra.

The main function of the bladder is the collection, temporary storage, and expulsion of urine. It has a unique muscular structure, and a complex neurological control, which shall be considered in detail. Embryologically, the bladder is derived from the hindgut. In this article, we shall look at the anatomy and physiological functions of the bladder.
