What is the stimulus of urination?
When the volume of urine reaches approximately 300 mL in adult,stretch receptors in the bladder wall transmit impulses to the central nervous system.That indidual then has a conscious desire to micturate. the afferent impulses enter the second,third,and fourth sacral segments of the spinal cord.Efferent impulses leave the cord from the same segments and pass via the parasympathetic preganglionic nerve fibers in the hypogastric plexuses to the bladder wall,where they synapse with postganglionic neurons.
What happens when the bladder gets too full?
When the bladder gets too full, it signals the brain to empty it by feeling the need to urinate. If the bladder continues to get overly full without being emptied, it can lead to discomfort, a feeling of urgency, and potentially leakage or urinary retention. In extreme cases, it can cause the bladder to stretch, leading to urinary incontinence or other bladder problems.
What part of the cortex is responsible for sensation of a full bladder?
The insular cortex is responsible for the sensation of a full bladder. This region is involved in processing internal bodily sensations, including feelings of fullness or emptiness. When the bladder is full, sensory information is sent to the insular cortex to signal the need for urination.
What anatomical structures does the water-containing balloon mimic?
The articular capsue containing synovial fluid inside.
How does bladder eliminate waste?
The bladder eliminates waste by storing urine produced by the kidneys until it is ready to be expelled from the body. When the bladder is full, nerve signals trigger the muscular walls of the bladder to contract, allowing urine to flow out through the urethra.
What is activated as urine accumulates in that bladder?
As urine accumulates in the bladder, stretch receptors in the bladder wall are activated. These receptors send signals to the brain to indicate that the bladder is full and needs to be emptied. This activates the urge to urinate.
A signal that the bladder is full is sent to the central nervous system by?
Stretch receptors in the bladder wall send signals to the central nervous system when the bladder is full. These receptors detect the stretching of the bladder as it fills up with urine, triggering the sensation of needing to urinate.
Why can t you feel wetness inside your body when your bladder is full - like we feel wetness on the outside?
The sensation of wetness is primarily a surface feeling, detected by skin receptors that respond to moisture. Inside the body, such as in the bladder, tissues are designed to contain fluids without the same sensory nerve endings that detect wetness. Instead, the bladder has stretch receptors that signal fullness or pressure, but not wetness. Thus, while you may feel the pressure of a full bladder, you don't experience the sensation of wetness internally.
What happens to the nerve ending when the bladder walls stretch?
When the bladder walls stretch due to filling with urine, specialized nerve endings called stretch receptors become activated. These receptors send signals to the brain indicating that the bladder is full, which triggers the urge to urinate. This process is part of the autonomic nervous system's regulation of bladder function, allowing for voluntary control over urination. As a result, the brain coordinates the relaxation of the bladder sphincter, facilitating the release of urine.
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.

Why does a full bladder cause increased migraine or headache pain?
Why does a full bladder cause headaches
Why cant you pee when your bladder is full?
It should be easier to pee when your bladder is full because there is more pressure on your bladder. If you are having trouble peeing, see a doctor.
Does a renal Ultrasound require a FULL bladder?
The need for a full bladder for an ultra scan is that the urine creates a window for the beams to pass though. It also helps any technicians know where everything is, and a full bladder also pushes organs so they are easily spotted.
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 better to have a full bladder with sonogram?
Yes, having a full bladder before a sonogram can help improve the quality of the images obtained. The full bladder pushes the uterus up and helps to provide a clearer view of the pelvic organs during the scan.
