Is the urine moved down to the ureters into the bladder by gravitational pull alone?
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.
What contractions enable body movements?
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.
How is the level of oxytocin controlled by a positive-feedback mechanism?
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.
What closes like a rubber band around the opening of the bladder?
The sphincter muscle closes like a rubber band around the opening of the bladder to prevent urine from leaking out. This muscle is controlled by nerves and can be consciously relaxed or contracted to release or hold urine in the bladder.
What is the function of the urteres?
The ureters are the collecting ducts for urine in the kidneys that transport urine to the bladder.
What type of muscles line the bladder to allow for contractions?
smooth muscle
What is an overactive bladder?
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.
Strategies to Manage an Overactive Bladder ?
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.
The muscle contractions that propel food through your intestines are controlled by what nervous system?
Autonomic
How does vesicare work?
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.
What is the treatment for overactive bladder?
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.
Is the urine moved down to the ureters into the bladder by gravitational pull alone?
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.
What is used to move urine from the kidneys to the bladdar through the ureters?
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.
What is the muscle that normally exhibits arrhythmic contractions?
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.
What is a function of the ureter?
The Ureter(s) [there are two of them] carry urine from the kidneys to the bladder.
What are three places where smooth muscles can be found?
