Which part of the brain is responsible for bladder filling?
The micturition center, which regulates the process of bladder filling and voiding is located in the pons of the brainstem (pontine micturition center). In general, the parasympathetic response stimulates bladder emptying, and the sympathetic response promotes bladder filling.
What is the posterior surface of the bladder?
The superior and part of the posterior surfaces of the bladder are covered by peritoneum. The inferior portion and inferolateral sides of the bladder are covered by endopelvic fascia. Anatomically, the bladder is contiguous with the ureters above and the urethra below.
How does the bladder relax when empty?
As an empty bladder fills with urine, mechanoreceptors detect the stretch in the wall of the detrusor muscle and send slow afferent fibers back to the spinal cord. This stimulates the sympathetic response on the detrusor and internal sphincter via the hypogastric nerves, causing them to relax and constrict, respectively. The parasympathetic response is inhibited at this time. Signals from the pudendal nerve to the external urethral sphincter are also stimulated to keep the external urethra contracted and closed. When the bladder becomes fully distended, sensory fibers travel to the pontine micturition center, stimulating the parasympathetic response and inhibiting the sympathetic tone to allow for contraction of the detrusor muscle and relaxation of the internal sphincter. Throughout this, somatic innervation to the external urethral sphincter remains tonically active to keep the sphincter contracted. When voiding is appropriate, activity from the pudendal nerve is inhibited to allow relaxation of the sphincter and the release of urine. Stimuli sent to the cortex during the filling process also play a role in voiding. The cortex processes emotional, sensory and social stimuli and acts on cells in the PMC and the periaqueductal gray (PAG) to prevent voiding until the appropriate time. [5]

How many ureters are there in the body?
Two ureters. These narrow tubes carry urine from the kidneys to the bladder. Muscles in the ureter walls continually tighten and relax forcing urine downward, away from the kidneys. If urine backs up, or is allowed to stand still, a kidney infection can develop. About every 10 to 15 seconds, small amounts of urine are emptied into the bladder from the ureters.
What tube allows urine to pass outside the body?
Urethra. This tube allows urine to pass outside the body. The brain signals the bladder muscles to tighten, which squeezes urine out of the bladder. At the same time, the brain signals the sphincter muscles to relax to let urine exit the bladder through the urethra.
