The neck of the bladder, or the posterior, division of the urethra, em braces that portion of the latter, which is situated between the external sphincter or the musculus compressor urethrw and the inner sphincter. The strength and the power of resistance of these two muscles are quite different. While the outer sphincter ofl'ers resistance, as well to the fluid secretion pressing from without onwards, as also to the fluid which endeavors to pass from within outwards, and while this resistance is overcome by the influence of the will, it 18 found, on the other hand, that the internal sphincter gives way before the slightest pressure, and therefore offers only a slight obstacle to either the passage of the urine from the bladder or back into the bladder from the posterior part of the urethra. The desire to urinate is due mostly to the fact that a large quantity of urine having collected in the bladder, the action of the inner sphincter is overcome and the urine then pressed into the neck. At the moment when the desire to micturate is greatest, the bladder and the neck become a common cavity, and the further progress of the urine is only hindered by the action of the will in keeping the external sphincter closed. The dissimilar action of these two sphincters is perceived when injections are thrown into the bladder. If we wish to force a fluid through the urethra into the bladder, without the aid of a catheter, and by means only of a hand syringe or an irrigator, we will find the greatest opposition at the musculus compressor urethroe, and in some cases it will be impossible to force the substance into the bladder, notwithstanding great force may be used, and, as a consequence of which, the fore-part of the urethra is painfully distended.
