Where is womans bladder located

The trigone of the bladder is a triangle region on the posterior wall. The two ureteric orifices ureteral opening where the ureters enter and internal urethral orifice where the urethra begins mark the three points of the trigone. It has a slight elevation known as the uvula of the bladder. The parts of the detrusor muscle towards the neck of the bladder form the internal urethral sphincter.

Some fibers run around the neck radially for better bladder control. This sphincter closes during ejaculation to prevent backward flow of semen into the bladder in men. The internal urethral sphincter is under involuntary control. The external urethral sphincter which is under voluntary control skeletal muscle is formed by the urogenital diaphragm.

Title: Urinary System, Female, Anatomy Description: Anatomy of the female urinary system; shows the right and left kidneys, the ureters, the bladder filled with urine, and the urethra.

In women, the bladder is bordered posteriorly by the uterus and vagina. Two sphincters—one internal and one external—at the base of the organ help keep urine in the bladder until nerve signals tell it to contract and release urine. A series of nerves controlled by the autonomic nervous system flow through the bladder, signaling when it is full and needs to be emptied.

Blood is supplied to the bladder at the top by the vesical artery and at the bottom by the vaginal or vesicular arteries. Smaller arteries—the inferior gluteal and obturator—also contribute. Blood drains from the bladder through the vesical veins, which flow to the iliac veins. This fluid travels from the kidneys down two ureters, one descending from each kidney to the bladder. The bladder serves as a reservoir to hold the urine until a reflex or conscious action—depending on age and ability—releases it.

The bladder itself is divided into four sections. The bladder is a very flexible organ made up of smooth muscle. Crisscrossed bands of smooth muscle form the detrusor muscle, the primary muscle of the bladder. The detrusor muscle works with the urinary sphincter to hold in or push out urine from the bladder through the urethra during urination. The bladder is the organ that holds urine until it is ready to be released and then helps to expel it from the body.

Ureters bring urine to the bladder from the kidneys, passing through an opening to the bladder called the ureterovesical junction. As the bladder fills with urine, nerves send signals to the central nervous system. Somatic and autonomic nerves control the detrusor muscle, which contracts and relaxes along with sphincters in the urethra. When full, the typical adult bladder can hold up to milliliters of urine at a time—or about 2 cups—which must be released every two to five hours.

Urination, or micturition, is a combination of voluntary and involuntary actions regulated by the micturition center—a signal center located in the pons of the brainstem. As the bladder fills and the bladder wall is stretched, sensors send nerve impulses to the micturition center.
