where are the urethral sphincters located?
481830
The internal urethral sphincter is made of a layer of smooth muscle that is surrounded by striated muscle. The external urethral sphincter is composed of striated muscle and is located distally and inferiorly to the bladder neck in women between the vaginal orifice and clitoris.

The vast majority of urinary tract infections (UTIs) are caused by the bacterium Escherichia coli (E. coli), usually found in the digestive system. Chlamydia and mycoplasma bacteria can infect the urethra but not the bladder. UTIs are given different names depending on where they occur.

A urinary tract infection (UTI) is an infection in any part of your urinary system — your kidneys, ureters, bladder and urethra. Most infections involve the lower urinary tract — the bladder and the urethra. Women are at greater risk of developing a UTI than are men.

The location of the kidneys The kidneys are situated below the diaphragm, one on either side of the spine. They are just below the rib cage.

Urinary tract infections typically occur when bacteria enter the urinary tract through the urethra and begin to multiply in the bladder. Although the urinary system is designed to keep out such microscopic invaders, these defenses sometimes fail.

Each ureter is a small tube, about 25 cm long, that carries urine from the renal pelvis to the urinary bladder. It descends from the renal pelvis, along the posterior abdominal wall, which is behind the parietal peritoneum, and enters the urinary bladder on the posterior inferior surface.

The penis and the urethra are part of the urinary and reproductive systems. The scrotum, testes (testicles), epididymis, vas deferens, seminal vesicles, and prostate comprise the rest of the reproductive system.

anal canal Thus, the internal sphincter is composed of smooth muscle and is innervated by the autonomic nervous system, while the external sphincters are of striated muscle and have somatic (voluntary) innervation provided by nerves called the pudendal nerves.

From the calyxes, pee travels out of the kidneys through the ureters (pronounced: YUR-uh-ters) to be stored in the bladder (a muscular sac in the lower belly). When a person urinates, the pee exits the bladder and goes out of the body through the urethra (pronounced: yoo-REE-thruh), another tube-like structure.

The true pelvis contains the pelvic colon, rectum, bladder, and some of the reproductive organs. The rectum is at the back, in the curve of the sacrum and coccyx; the bladder is in front, behind the pubic symphysis. In the female, the uterus and vagina occupy the interval between these viscera.

The ureters are bilateral thin (3 to 4 mm) tubular structures that connect the kidneys to the urinary bladder, transporting urine from the renal pelvis into the bladder. The muscular layers are responsible for the peristaltic activity that the ureter uses to move the urine from the kidneys to the bladder.

The Female Urethra Is Shorter Than the Male Urethra Urine produced in the kidneys passes through the ureters, collects in the bladder, and is then excreted through the urethra. In females, the urethra is narrow and about 4 cm long, significantly shorter than in males.

Male urinary system A urinary tract infection (UTI) is an infection in any part of your urinary system — your kidneys, ureters, bladder and urethra. Most infections involve the lower urinary tract — the bladder and the urethra. Women are at greater risk of developing a UTI than are men.

In males, the urethra is 8 inches long, while in females, the urethra is only 2 inches long. So the primary difference is one of length. Another difference would be the path the urine takes getting from the bladder to the external world. In females, the path is more direct, while in males, the path is more curving.

Ureters are tube-like structures that connect the kidneys with the urinary bladder. Each ureter arises at the renal pelvis of a kidney and travels down through the abdomen to the urinary bladder. ... The urethra is a tube that connects the urinary bladder to the external urethral orifice.

Muscles. The detrusor muscle is located within the walls of the bladder and is composed of smooth muscle fibers that are longitudinal and circular. The layers of the detrusor muscle start longitudinally in the inner layer, become circular in the middle layer, and then longitudinal again in the outer layer.
