Manneken Pis depicts a<unk> g boy (puer mingens).<unk>  is the release of urine from the urinary bladder through the urethra to the outside of the body. It is the urinary system's form of excretion. It is also known medically as micturition, voiding, uresis, or, rarely, emiction, and known colloquially by various names including peeing, weeing, and pissing. In healthy humans (and many other animals), the process of<unk>  is under voluntary control. In infants, some elderly individuals, and those with neurological injury,<unk>  may occur as a reflex. It is normal for adult humans to urinate up to seven times during the day. In some animals, in addition to expelling waste material,<unk>  can mark territory or express submissiveness. Physiologically,<unk>  involves coordination between the central, autonomic, and somatic nervous systems. Brain centres that regulate<unk>  include the pontine micturition center, periaqueductal gray, and the cerebral cortex. In placental mammals, urine is drained through the urinary meatus, a urethral opening in the male penis or female vulval vestibule.
