To the urinal

The bladder, when empty, is the size of a tennis ball, but slowly fills up with urine to 250-400 cubic centimeters. At that moment, the nerves that govern the urinary system send an electrical signal to the brain: the brain understands that the bladder is full and we immediately feel the urge to urinate. The brain then sends two commands: on the one hand, it commands the muscles of the bladder to contract so that the urine flows out into the urethra, and on the other, it commands the sphincters to relax so that they open the hole in the urethra that they had kept closed until then and the urine flows out. There are

people who feel the saliva before the bladder fills. They suffer from incontinence and it is usually caused by the failure of one of the two mentioned processes: for example, if the bladder contracts when it is not needed due to hyperactivity, it causes the urine to escape; the same happens when due to a defect in the sphincter the hole is not kept completely closed when the abdominal pressure increases, such as coughing, laughing or due to other effort. In other cases, it is usually due to neurological problems, because the electrical signal that controls the process does not arrive well, as in cases of Parkinson's, dementia or depression, or prostate problems, urinary and vaginal infections, diabetic imbalance, excessive medication, cancer or, of course, multiple births.
