    The bladder may be regarded as essentially a hollow expansion of mucous membrane continuous with that of the ureters behind and the urethra in front; the exter- nal surface of this sac is overlaid with bands of muscu- lar fibres, the unstriped and involuntary variety, dis- posed in figure-of-8 spiral loops, vertically, obliquely, and horizontally ;* springing, for the most part, from the neck of the bladder, to be presently noticed, these muscular bands are thus entwined over and around the organ, leaving intervals of mucous mem- brane uncovered ; a layer of cellular tissue intervenes between the two, this submucous texture containing an abundance of the finely coiled fibres of elastic tissue. The muscular arrangement forms the “detrusor urinae” muscle, and a marked band around the neck of the bladder is named “ sphincter vesicge.” Blood-vessels are plentifully supplied to the bladder, and have the following distribution :—The internal iliac artery (see Fig. 2), from its anterior division, gives off the superior and inferior vesical branches, and in the female the uterine arteries also, all of which ramify and terminate in the cellular texture and mucous mem- brane ; the veins form large plexuses, situated chiefly at the neck, sides, and base of the bladder, and, terminat- ing in the internal iliac veins, are accompanied in their course by lymphatic vessels, which enter lymphatic- glands around the internal iliac artery, and thence pro- ceed upwards to the lumbar glands. Nerves are sup- plied in equal abundance. They proceed partly from the * Original Dissections by J. Bell Pettigrew, Museum Roy. Coll, of Surgeons Eng., and, same authority, “ On the Muscular Arrangements of the Bladder and Urethra,” &c., ‘ Phil. Trans.,’ 1867.
