Question
Chapter 24.8, Problem 39WDYL
Summary Introduction
To analyze:
The steps that lead to micturition and the point at which micturition reflex overpowers conscious control.
Introduction:
The process of expulsion of urine from the urethral opening is termed micturition. This process is associated with the release of the stored urine in the bladder. This process is regulated by the reflexes initiated by the nervous system.
