In some animals, in addition to expelling waste material, urination [[#Other animals|can mark territory or express submissiveness]]. Physiologically, urination involves coordination between the [[central nervous system|central]], [[autonomic nervous system|autonomic]], and [[somatic nervous system]]s. Brain centres that regulate urination include the [[pontine micturition center]], [[periaqueductal gray]], and the [[cerebral cortex]].
