Urination is the release of urine from the bladder to the outside of the body. Urine is released from the urethra through the penis or vulva in placental mammals[1][2]: 38, 364 and through the cloaca in other vertebrates.[3][1] It is the urinary system's form of excretion. It is also known medically as micturition,[4]voiding, uresis, or, rarely, emiction, and known colloquially by various names including peeing, weeing, pissing, and euphemistically going (for a) number one. The process of urination is under voluntary control in healthy humans and other animals, but may occur as a reflex in infants, some elderly individuals, and those with neurological injury. It is normal for adult humans to urinate up to seven times during the day.[5]
In some animals, in addition to expelling waste material, urination can mark territory or express submissiveness. Physiologically, urination involves coordination between the central, autonomic, and somatic nervous systems. Brain centres that regulate urination include the pontine micturition center, periaqueductal gray, and the cerebral cortex.
