ANATOMY

Detailed explanation-1: -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.

Detailed explanation-2: -Bladder emptying is known as urination.

Detailed explanation-3: -Normal micturition occurs when bladder contraction is coordinated with urethral sphincter relaxation. ). In addition to normal urinary function, continence and normal voiding require normal cognitive function (including motivation), mobility, access to a toilet, and manual dexterity.

Detailed explanation-4: -Normal micturition occurs when bladder contraction is coordinated with urethral sphincter relaxation. The CNS inhibits voiding until the appropriate time and coordinates and facilitates input from the lower urinary tract to start and complete voiding. The sympathetic system contracts the smooth muscle sphincter.

Detailed explanation-5: -For people under the age of 50, 60mL of urine or less is left in the bladder after voiding. Due to the natural loss of continence as you age, those over the age of 50 years usually have a postvoid residual amount of 100mL or less.
