Mechanism of micturition

Introduction 11 12 13 14 15 definition of the mechanism use of function of the mechanism general statement of the principle governing its operation physical description of the mechanism principal parts which make up the mechanism 2. Micturition: process by which urinary bladder empties it is a complex act involving both autonomic & somatic nerve pathways & several reflexes that can be either inhibited or facilitated by higher centers in the brain.

Pontine micturition center (pmc) is located in gray area of the pons, and is the area of integration and control of afferent and efferent impulses from the urinary bladder the pontine continence center (pcc) is located in reticular formation of the pons. Mechanism of micturition, voiding dysfunction functions of bladder collection, storage of urine (↓ pressure) bladder wall able to stretch, rearrange. Filling of the bladder and the micturition reflex the ureters carry urine from the kidney to the bladder it penetrates the detrusor muscle of the bladder wall, which can also compress the ureters during urination to prevents urine from the bladder emptying into the ureters (vesicoureteral reflux.

Micturition reflex is the neurological pathways involved in urination when your bladder fills, the detrusor muscles expand and proprioceptors within the walls of the muscle activate it sends signals (afferent nerves) that go to your medulla and also to the parasympathetic system in the sacral spinal cord.

Mechanism of micturition

mechanism of micturition Physiology of micturation micturation is the discharge of urine from the bladder via the urethra this page continues from the general description of the human bladder and the separate labeled diagrams of the male and female bladder and urethra.

Hence it is very essential to learn about mechanism of normal labor, its principles and steps to distinguish it from an abnormal one definition: the series of movements that occur on the head in the process of adaptation, during its journey through the pelvis, is called mechanism of labor1 principles the principles are common to all mechanisms. Meanwhile, the sphincter mechanism remains closed under autonomic and somatic nervous system control during urination, the inhibition of contractions is removed and a reflex originates in the pontine micturition center that causes the detrusor muscle to contract and the sphincter mechanism to relax. Urination 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 it is also known medically as micturition, voiding, uresis, or, rarely, emiction, and known colloquially by various names including peeing, weeing, and pissing.

  • Injury to the pontine micturition center will compromise the smooth coordination between sphincter mechanism and detrusor muscle, and injury to the brain will affect the volitional control of urine (bladder stability) see also urinary incontinence.
  • The physiology of micturition 22 july, 2003 urine production and excretion are vital for a normal healthy life (mclaren, 1996).
