Question: What Is The Trigone?

What are Vasa recta?

The vasa recta, the capillary networks that supply blood to the medulla, are highly permeable to solute and water.

The ability of the vasa recta to maintain the medullary interstitial gradient is flow dependent.

A substantial increase in vasa recta blood flow dissipates the medullary gradient..

Why is Trigone medically important?

Precise connections between ureters and the trigone are crucial for function of the valve mechanism that prevents back flow of urine from the bladder to the ureters, a major cause of reflux and obstruction, which can damage the kidney and cause severe health problems including end-stage renal disease.

What are common bladder problems?

Signs of a bladder problem can include:Inability to hold urine or leaking urine (called urinary incontinence)Needing to urinate eight or more times in one day.Waking up many times at night to urinate.Sudden and urgent need to urinate.Pain or burning before, during, or after urinating.Cloudy or bloody urine.More items…

Which gender has a bigger bladder?

The detrusor is thicker in men than women, as greater voiding pressure is needed to empty the bladder through the longer urethra of males [7].

Why is the trigone of the urinary bladder clinically important quizlet?

Why is the trigone of the urinary bladder clinically important? Infections tend to persist in the trigone. Urine moves down the ureters into the bladder due to gravitational pull alone. Urine may routinely contain sodium, potassium, proteins, and red blood cells.

Is the bladder a muscle?

Ureters are thin tubes of muscle that carry urine from each of the kidneys to the bladder. Located in the pelvis between the pelvic bones, the bladder is a hollow, muscular, balloon-shaped organ that expands as it fills with urine.

What is the Trigone quizlet?

trigone. triangular region of the internal urinary bladder formed by two urethral orifices and the internal urethral orifice (stretch receptors)

What three structures define the Trigone?

What is the main function of the distal tubule?

The distal convoluted tubule is the nephron segment that lies immediately downstream of the macula densa. Although short in length, the distal convoluted tubule plays a critical role in sodium, potassium, and divalent cation homeostasis.

What nerves affect the bladder?

The lower urinary tract is innervated by 3 sets of peripheral nerves: pelvic parasympathetic nerves, which arise at the sacral level of the spinal cord, excite the bladder, and relax the urethra; lumbar sympathetic nerves, which inhibit the bladder body and excite the bladder base and urethra; and pudendal nerves, …

What are the four main organs of the urinary system?

The urinary system’s function is to filter blood and create urine as a waste by-product. The organs of the urinary system include the kidneys, renal pelvis, ureters, bladder and urethra.

What causes Trigonitis?

Sometimes it’s due to benign cellular changes in the trigone. Medically, these changes are called nonkeratinizing squamous metaplasia. This results in a condition called pseudomembranous trigonitis. These changes occur due to hormonal imbalances, particularly the female hormones estrogen and progesterone.

How long does it take to do a cystoscopy?

A simple outpatient cystoscopy can take five to 15 minutes. When done in a hospital with sedation or general anesthesia, cystoscopy takes about 15 to 30 minutes. Your cystoscopy procedure might follow this process: You’ll be asked to empty your bladder.

What are the 3 layers of the bladder?

The wall of the bladder wall has three principal tissue layers or coats:mucosa.submucosa.muscularis.

What is the trigone of the bladder?

The trigone (a.k.a. vesical trigone) is a smooth triangular region of the internal urinary bladder formed by the two ureteric orifices and the internal urethral orifice.

Where is the Trigone located?

Trigone. The trigone is a triangular portion of the bladder floor bordered (ventrally) by the internal urethral opening or bladder neck and (dorsolaterally) by the orifices of the right ureter and left ureter.

Is Trigonitis curable?

Following the treatment, 30% of patients considered themselves cured and 41% reported symptom improvement. On follow-up cystoscopy in 31 patients, trigonitis was completely resolved in 8 cases and improved in 12 cases.

What contains the Trigone?

On the superior surface, the outer layer of the bladder wall is parietal peritoneum. … There is a triangular area, called the trigone, formed by three openings in the floor of the urinary bladder. Two of the openings are from the ureters and form the base of the trigone.
