Urination
Urination, also known medically as micturition, voiding, uresis, or, rarely, emiction, and known colloquially by various names including tinkling, peeing, weeing, and pissing, is the release of urine from the urinary bladder through the urethra to the outside of the body. In healthy humans (and many other animals) the process of urination is under voluntary control. In infants, some elderly individuals, and those with neurological injury, urination may occur as an involuntary reflex. In other animals, in addition to expelling waste material, urination can mark territory or express submissiveness. Physiologically, micturition involves coordination between the centralautonomic, and somatic nervous systems. Brain centers that regulate urination include the pontine micturition centerperiaqueductal gray, and the cerebral cortex. In male placental mammals, urine is ejected through the penis. In female placental mammals (with some exceptions, including female galagos, female spider monkeys, and female spotted hyenas, which urinate through a pseudo-penis), urine is ejected through the vulva.

Micción
La orina se forma continuamente en el riñón y llega a la vejiga intermitentemente gracias al peristaltismo o serie de contracciones de los uréteres. Unas válvulas impiden el retroceso de la orina desde la vejiga a los uréteres. Cuando la vejiga ha acumulado medio litro de orina, la llegada de nuevo orina aumenta notablemente la presión de la vejiga. Se pone en funcionamiento, en consecuencia, un mecanismo que facilita la evacuación. Existe en la vejiga terminales nerviosas receptores de la distensión de la misma. Se originan impulsos nerviosos que llegan a la región sacra de la médula espinal. Aquí excitan a unas fibras nerviosas que obligan a contraer la pared de la vejiga y a abrir el esfínter interno. A la vez, la corriente nerviosa llega a los centros superiores, y se produce el deseo consistente de orinar. Periódicamente y de forma voluntaria se abre el esfínter externo dando salida a la orina. Es el proceso de micción.

Miction
La miction (du latin , « uriner », parfois improprement orthographié mixion), l'action d'uriner, désigne l'élimination d'urine par la vidange de la vessie. Comme beaucoup de fonctions liées à la génitalité humaine, la miction est désignée par de nombreux termes familiers et argotiques, comme pisser ou petite commission (par opposition à la grosse commission).
