Section A lies at a higher level than B. upward prolongation of the sheath is continuous with the fascial layers which enclose the ampullse of the ductus deferentes and the seminal vesicles, and it is adherent to the peritoneum of the recto-vesical pouch. In this position it is often spoken of as the recto-vesical fascia. Structure of the Prostate.—Beneath the fibrous sheath of the gland the superficial part of the prostate is seen to be largely composed of matted interlacing bundles of smooth muscle and connective tissue fibres, which form a kind of capsule for the deeper parts of the organ. This layer, or capsule of the prostate, is not sharply defined, but from its deep aspect fibrous and muscular strands pass inwards, converging towards the posterior wall of the urethra, to become continuous with the mass of smooth muscular tissue which surrounds this canal as it traverses the prostate. These somewhat radially arranged strands divide the prostate into a number of incompletely defined lobules, of which there appear to be about fifty. The yellowish-coloured glandular tissue, or corpus glandulare, which forms the lobules is composed of minute, slightly branched tubules, the walls of which in certain places show numerous saccular dilatations. In the upper portion of the gland the tubules are slightly dilated and shorter than in the lower part, where they are longer and more convoluted. The glandular tubules lead into the minute prostatic ducts, which open into the urethral canal as it traverses the prostate. The ductus prostatici number about twenty or thirty, and open for the most part into a groove on each side of the median elevation, or crista urethralis, in the posterior wall of the urethra (Fig. 1023 a). The bulk of the glandular tissue is situated at the sides of and behind the urethra. In front of the upper pa
