micturition center造句

• Brain centers that regulate urination include the pontine micturition center, periaqueductal gray, and the cerebral cortex.
• The pontine micturition center also causes inhibition of Onuf's nucleus, resulting in relaxation of the external urinary sphincter.
• Bladder afferent signals ascend the spinal cord to the periaqueductal gray, where they project both to the pontine micturition center and to the cerebrum.
• Once the voluntary signal to begin voiding has been issued, neurons in pontine micturition center fire maximally, causing excitation of sacral preganglionic neurons.
• Another possibility is the excitation or disinhibition of neurons in the pontine micturition center, which causes concurrent contraction of the bladder and relaxation of the sphincter.
• Other output regions include : the ventromedial hypothalamus, medial and lateral septal nuclei, central medial amygdala, zona incerta, periaqueductal gray matter, lateral habenula, diagonal band, substantia innominata ( contains the nucleus basalis ), stria terminalis, prefrontal cortex, various brain stem substructures, including the rostral ventromedial medulla, rostral ventrolateral medulla, nucleus ambiguus, solitary nucleus, spinal trigeminal nucleus, pontine micturition center, ventral respiratory group, and pontine respiratory group ), area postrema, and dorsal nucleus of vagus nerve.
