What is micturition in anatomy?
Definition of micturition. : the act or process of micturating : urination As the bladder fills, spinal sensory afferents relay this information to a region in the pons that coordinates micturition. — Susan Iversen et al.
What does frequency of micturition mean?
frequency of micturition. fre·quen·cy of mic·tu·ri·tion. micturition at short intervals; it may result from increased urine formation, decreased bladder capacity, or lower urinary tract irritation.
What are micturition disorders?

What is the most common word for micturition?
Urination, also known as micturition, is the release of urine from the urinary bladder through the urethra to the outside of the body. It is the urinary system's form of excretion.

What is micturition answer in one sentence?
Micturition is a process where urine is expelled from the body. Animals and humans have a specialised system of organs known as the excretory system to eliminate the waste products from the body. In other words, the process of expelling urine from the body is called micturition.
What is the difference between urination and micturition?
Micturition, also known as urination, is the ejection of urine from the urinary bladder through the urethra to the outside of the body. In healthy humans the process of urination is under voluntary control.
Which part of the brain controls micturition?
the ponsThe mechanical process of urination is coordinated by the pons in the area known as the pontine micturition center (PMC). The conscious sensations associated with bladder activity are transmitted to the pons from the cerebral cortex.
What triggers micturition?
When the bladder is full of urine, stretch receptors in the bladder wall trigger the micturition 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.
What are the stages of micturition?
Introduction. Micturition is the process of eliminating water and electrolytes from the urinary system, commonly known as urinating. It has two discrete phases: the storage/continence phase, when urine is stored in the bladder; and the voiding phase, where urine is released through the urethra.
What are 3 phases of normal micturition?
Bladder Emptying and the Micturition Reflex relaxation of the striated sphincter (somatic innervation) relaxation of the smooth muscle sphincter and opening of the bladder neck (sympathetic innervation) detrusor contraction (parasympathetic innervation)
How do you control micturition?
To retrain your bladder, your doctor will advise you to follow a regular bathroom schedule. Try holding off for 10 minutes after the initial urge to go. Your doctor may encourage you to gradually increase the length of time between each bathroom visit. Try to avoid emptying your bladder between visits.
What is micturition quizlet?
Definition of micturition. The process of filling the bladder until it reaches a threshold level at which the autonomic micturition reflex results in emptying of the bladder, or if it fails, the conscious desire to urinate.
What does anuria mean?
Anuria, sometimes called anuresis, refers to the lack of urine production. This can happen as a result of conditions like shock, severe blood loss and failure of your heart or kidneys. It can also be due to medications or toxins. Anuria is an emergency and can be life-threatening.

Painful urination (dysuria) is discomfort or burning with urination, usually felt in the tube that carries urine out of your bladder (urethra) or the area surrounding your genitals (perineum).
What is the process of micturition?
Micturition or urination is the process of emptying urine from the storage organ, namely, the urinary bladder. The detrusor is the smooth or involuntary muscle of the bladder wall. The urethral muscles consist of the external and internal sphincter.
What is the process of urination?
The Urinary Process . Urination is a complex process controlled by muscles of the bladder and sphincter mechanism and by modulatory centers in the central and peripheral nervous systems. The detrusor muscle is a complex meshwork of interlaced smooth muscle bundles that contract in a way that squeezes urine from the bladder vesicle. The sphincter mechanism consists of smooth muscle in the bladder neck and proximal urethra, a striated muscle sphincter consisting of slow twitch muscle fibers in the urethral wall, and periurethral muscles that are a component of the pelvic floor muscles. The detrusor relaxes during bladder filling to accommodate increasing volumes at a low pressure, and the sphincter remains tightly closed. During urination, the detrusor contracts and the sphincter mechanism relaxes, allowing smooth outflow of urine.
What is the term for the discharge of urine from the kidneys?
Called also micturition and voiding.
What is the treatment for micturition syncope?
A number of medications have been studied as possible treatments for micturition syncope, including drugs that stabilize blood pressure and medications used to treat chest pain, high blood pressure, and heart failure.
What does it mean when you faint while urinating?
Micturition syncope is the medical term for fainting (syncope) while urinating or right after urinating (micturition). These events are rarely a sign of a serious medical condition. Almost always, the loss of consciousness does not last long. In most cases, injuries from falling during loss of consciousness are of greater concern.
Does low blood pressure cause micturition syncope?
While not entirely clear, doctors believe that a low blood pressure and slow heart rate play a role in micturition syncope.
Can medications cause micturition syncope?
Certain medications and drugs can cause or contribute to micturition syncope.
Can you have micturition syncope every time you pee?
If you experience micturition syncope, it likely won’t happen every time you urinate. In fact, it can be a one-time experience. It’s more likely to occur if you’ve been drinking alcohol, getting up from sleeping, or are tired, hungry, or dehydrated.
Is micturition syncope serious?
