What is micrition urination?

Answer 1

The word is "Micturition" and it means the same thing as urination, though years ago it used to mean excessive urination, and before that it meant the desire to urinate. Words tend to evolve in a living language.

Urination is the act of allowing urine to flow out of the bladder and body via the urethra, which requires a conscious decision to do so in most people. It is actually very complex, involving several areas of the brain, spinal cord, and systems of nerves running to the bladder and both internal and external sphincters (rings of muscle) around the urethra.
