6. Explain micturition.​

Answer 1

$\huge\bold\red{Answer!}$

Micturition

Micturition or urination is the process of expelling urine from the bladder.

This act is also known as voiding of the bladder.

The process of micturition is regulated by the Nervous System and the muscles of the bladder and Urethra.

The urinary bladder can store around 350-400 ml of urine before it expels it out.

Cause of Micturition

Micturition syncope is fainting during or, more commonly, immediately after urination due to a severe drop in blood pressure.

Micturition syncope is most common in older men and usually occurs at night after a deep sleep.

The exact cause of micturition syncope isn't fully understood.

Process of Micturition

During micturition, parasympathetic stimulation causes the detrusor muscle to contract and the internal urethral sphincter to relax.

The external urethral sphincter is under somatic control and is consciously relaxed during micturition.

In Infants, Voiding occurs Involuntarily (as a reflex).
