Mikturitsiooni

Mikturitsiooni, also known as "micturition," is the process by which the body expels urine from the bladder. This process is primarily controlled by the autonomic nervous system, which regulates the muscles of the bladder and urethra. The bladder stores urine produced by the kidneys, and the urge to urinate, or micturition reflex, is triggered when the bladder reaches a certain volume or pressure. This reflex is mediated by the detrusor muscle, which contracts to expel urine, and the internal urethral sphincter, which relaxes to allow urine to flow out.

Micturition is a normal and essential bodily function that helps maintain fluid balance and remove waste products from the body. However, disruptions in this process can lead to various urinary tract disorders, such as urinary incontinence, urinary retention, and urinary tract infections. Medical interventions, such as catheterization and bladder training, may be employed to manage these conditions.

The study of micturition involves various disciplines, including urology, physiology, and neuroscience. Researchers explore the mechanisms underlying the micturition reflex, the role of the autonomic nervous system, and the factors that can influence bladder function. Understanding micturition is crucial for developing effective treatments for urinary tract disorders and improving the quality of life for individuals with these conditions.
