THORAX ABDOMEN AND PELVIS

Detailed explanation-1: -The micturition reflex involves a coordinated and sustained contraction of the detrusor muscle (the detrusor reflex) along with simultaneous relaxation of the urethra. Moreover, depending on the size of the bladder, the micturition reflex may also result in urine storage.

Detailed explanation-2: -What is Micturition? Micturition is a process where urine is expelled from the body. Animals and humans have a specialised system of organs known as the excretory system to eliminate the waste products from the body. In other words, the process of expelling urine from the body is called micturition.

Detailed explanation-3: -One of the signals going the other way, from the brain to the bladder, is the activation of a part of the brainstem called the PMC, short for pontine micturition center. (The word ‘micturition’ originally referred to the urge to urinate, but is now often used to describe the process of urination as well).
