If urination is not convenient, the brain sends impulses down the spinal cord to inhibit the micturition reflex- this statement is true.
Bladder filling activates stretch receptors, initiating the micturition reflex, a spinal reflex under control of higher central nervous system centers. Bladdertone is defined by the relationship between bladder volume and internal (intravesical) pressure.
The brain stem is located at the base of the skull.
Within the brain stem is the pons, a specialized area that serves as a major relay center between the brain and the bladder (see the image below).
The pons is responsible for coordinating the activities of the urinary sphincters and the bladder.
