They are stretch receptors. As your bladder fills, these receptors are gradually stretched until they reach a stretch level high enough to enter your consciousness as a need to urinate.

What is the job of the urinarybladder?
The function of the urinary bladder is to act as a reservoir of urine. The kidneys filter the blood of waste products and the urine produced trickles down the two tubes called ureters which open in the bladder. Once the bladder is full, stretch receptors convey the sensation and creates a desire and urge to pass urine to empty the bladder.
Stretch of a full urinary blades is detected by?
When the bladder is full of urine, stretch receptors in the bladder wall trigger the 'need to go' reflex. The detrusor muscle that surrounds the bladder contracts. The internal urethral sphincter relaxes, allowing for urine to pass out of the bladder into the urethra. Both of these reactions are involuntary. The external urethral sphincter is voluntary. It must be relaxed for urine to flow through the urethra and outside the body.

Is it better to have a full bladder with sonogram?
It depends from the examined area. For an ultrasound of your pelvic, bladder or kidneys, your bladder must be REALLY chock-full. Its rather uncomfortable, but neccessary ;)
How are waste transported to the kidneys?
down to the bladder via the uriters, then out. Urine from each kidney drains through a tube called a ureter and collects in the bladder. As the bladder fills, its muscular wall stretches. When it is full, receptors in the wall send a signal to the brain and trigger the urge to urinate. During urination the muscles that close the bladder exit relax to release the urine.
Is a ureter were uren is stored?
No. Urine is stored in the bladder until the bladder is full. The ureters are the tubes that carry the urine from the kidneys to be stored in the bladder. And then when the bladder is full, the urine travels through the urethra to outside of the body.
Is it very uncomfortable to get an ultrasound with a full bladder?
Oh yes, trust me! You have to drink tons of water until your bladder is very, very full, then hold it in until the exam is over.

A full bladder triggers an urgency to urinate. If you don't urinate within a reasonable amount of time, the bladder can overfill and backflow to the kidneys, which can cause serious problems.
What is emptying the bladder controlled by?
The micturition reflex tells you when you need to empty your bladder. This happens on average four to eight times a day. The reflex is controlled by your central nervous system. When your bladder is about half full, the stretch receptors in the walls of your bladder become active and send signals along your pelvic nerves to your spinal cord. A reflex signal is sent back to your bladder, which makes the detrusor muscle in the bladder wall contract. The contraction increases the pressure in your bladder, and this is what makes you want to pass urine. Because the external sphincter is under voluntary control, you don't urinate until you decide to relax this muscle. simple answer would be this; Sphincter muscle that surrounds the urethra.
