Sep 13, 2023 · Urination or micturition removes metabolic products and toxic wastes filtered from the kidneys and is a vital human bodily function. The micturition reflex requires a complex network of signals between the nervous system and the urinary tract.

Micturition (urination) is the process of urine excretion from the urinary bladder. Micturition has two discrete phases: thestorage/continence phase, when urine is stored in the bladder; and the voiding phase, where urine is released through the urethra.

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.

May 1, 2023 · The physiology involved in bladder function and micturition is exceedingly complex, integrating the autonomic nervous system, the central nervous system, the somatic nervous system, and neurohormonal modulation.

Micturition Reflex. Micturition is the physiological term for urination or voiding. It results from an interplay of involuntary and voluntary actions by the internal and external urethral sphincters. When bladder volume reaches about 150 mL, an urge to void is sensed but is easily overridden.

Physiology of Micturition. Physiologically, micturition involves the coordination of the central, autonomic, and somatic nervous systems. The brain centers that regulate urination include the pontine micturition center, the periaqueductal gray, and the cerebral cortex, which cause both involuntary and voluntary control over micturition.

Feb 6, 2005 · Fibres that project to the frontal cortex allow social and conscious control over micturition. The ‘micturition centre’ is thought to act as a final common pathway and controls the coordinated voiding process involving bladder outlet relaxation and detrusor contraction.

Control of micturition Children and adults have considerable control over when and where they pass urine. They can also increase or decrease the rate of flow and even stop and start again, so micturition is

The whole micturition cycle should be thought of in two discrete phases and processes. Storage (filling) Accommodation of increasing volumes of urine at low pressure with normal compliance. Appropriate sensation of filling. Closed bladder outlet at rest which stays closed during rises in intra-abdominal pressure.

Urination or micturition removes metabolic products and toxic wastes filtered from the kidneys and is a vital human bodily function. The micturition reflex requires a complex network of signals between the nervous system and the urinary tract.
