-[urination] 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 urination is under voluntary control)
(in infants, some elderly individuals, and those with neurological injury, urination may occur as a reflex)
(it is normal for adult humans to urinate up to 7 times during the day)
(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 centers that regulate urination 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’ / female ‘vulval vestibule’)
