Bladder contractions are primarily controlled by the autonomic nervous system, specifically the parasympathetic nervous system. When the bladder fills, stretch receptors send signals to the brain, which then triggers the detrusor muscle to contract and facilitate urination. This process is also influenced by various neurotransmitters, with acetylcholine playing a key role in stimulating bladder contractions.
The flow of excretory waste from the kidneys to the bladder is primarily controlled by the ureters, which are muscular tubes that transport urine via peristaltic contractions. These contractions push urine from the renal pelvis of each kidney through the ureters and into the bladder. Additionally, the ureteral openings are equipped with valves that prevent backflow, ensuring a one-way flow of urine. The bladder then stores the urine until it is expelled from the body during urination.
No, urine is moved down to the ureters into the bladder by peristaltic contractions of the smooth muscles in the walls of the ureters. The muscles contract in a wave-like motion to push the urine towards the bladder.
Urine that flows from the ureters to the bladder is a liquid waste product produced by the kidneys during the filtration of blood. The ureters are muscular tubes that transport this urine through peristaltic contractions to the urinary bladder, where it is stored until excretion. This process is crucial for maintaining the body's fluid and electrolyte balance.
Muscles in the body enable movements through contractions. These contractions occur when muscle fibers shorten and generate force, allowing for various movements such as walking, stretching, and flexing. The coordinated efforts of different muscle groups contracting and relaxing result in smooth and controlled body movements.
Oxytocin release is controlled by a positive-feedback mechanism during childbirth. When contractions of the uterus stimulate oxytocin release, this hormone further intensifies contractions, leading to more oxytocin release. This cycle continues until the baby is delivered.

Physicians usually have massive amounts of literature covering this problem. There are dozens of internet sites with bladder information ,or your local library, friends and relatives are another good source of information.
An overactive bladder is a medical condition characterized by the involuntary and sudden contraction of the urinary bladder muscles. The contractions cause a relentless need to urinate throughout the day and night. The contractions occur regardless of whether your bladder is filling. Contractions can cause urinary incontinence if they are triggered when your bladder is full. There are several ways to control your bladder and eliminate the inconvenience and distress of this disorder. Kegel exercises are an excellent method for controlling an overactive bladder. These exercises strengthen the muscles that control urination. You can discretely perform these exercises as you sit at your desk or recline on your bed. Physicians usually recommend that you supplement these exercises with a regimen designed to retrain your bladder. The purpose of this regimen is to resist the urge to urinate in response to the contractions. You will use scheduled voiding to limit your trips to the bathroom to specific times. This systematic reconditioning of your mind will help you reestablish control of your bladder. Over time, the contractions will diminish or resolve completely. In addition to Kegel and mind-bladder reconditioning exercises, your physician can explore the underlying reason for frequent urination and an overactive bladder. There may be other issues if you urinate more than eight times in a single day. A thorough physical and review of your current medications can eliminate potential risk factors that interfere with normal bladder function. Your physician can prescribe medication to manage overactive bladder issues. If you prefer natural remedies, you can try herbs with a reputation for alleviating this problem. Cayenne can lower the sensitivity of the nerves in your bladder. It can also moderate the force and the incidence of contractions. Chamomile, ginger root and peach bark reduce infections that make your bladder hyperactive. There is a potential for interactions between prescription medications and herbal remedies. Consult your physician if you are taking more than one prescription medication or are taking herbal remedies for an overactive bladder or another medical condition.
Vesicare (solifenacin) works by blocking certain receptors in the bladder, called muscarinic receptors. By doing so, it reduces bladder muscle contractions and helps to control symptoms of overactive bladder, such as frequent urination, urgency, and incontinence.
Medications can reduce many types of leakage. Some drugs inhibit contractions of an overactive bladder. Others, such as solifenacin succinate (Vesicare), relax muscles, leading to more complete bladder emptying during urination.
Autonomic
Urine is transported into the bladder through the ureters, which are two thin tubes that connect the kidneys to the bladder. As the kidneys filter blood, they produce urine, which then flows down the ureters via peristaltic contractions. The urine is stored in the bladder until it is expelled from the body during urination.
No, urine is moved down to the ureters into the bladder by peristaltic contractions of the smooth muscles in the walls of the ureters. The muscles contract in a wave-like motion to push the urine towards the bladder.
The ureters move urine from the kidney to the bladder by something known as peristalsis. This is a wave like series of muscle contractions. The lining of smooth muscles in the ureter move the urine to the bladder.
The Ureter(s) [there are two of them] carry urine from the kidneys to the bladder.
The heart muscle is the muscle that normally exhibits arrhythmic contractions. These contractions are controlled by the heart's internal pacemaker system, which generates electrical signals to regulate the heart rate and rhythm.
