Structure of the Pancreas. The pancreas is built on the type of compound tubular or acino-tubular glands, and in its general arrangement into lobes, lobules andsystem of ducts and acini, it corresponds exactlyto the true salivary glands. The epitheliumlining the ducts is not at all, or only faintly,striated. The acini are tubular or flask -shaped, and often convoluted.

Structure of the Pancreas. The pancreas is built on the type of compound tubular or acino-tubular glands, and in its general arrangement into lobes, lobules andsystem of ducts and acini, it corresponds exactlyto the true salivary glands. The epitheliumlining the ducts is not at all, or only faintly,striated. The acini are tubular or flask -shaped, and often convoluted. They consist ofa membrana propria, resembling that of thesalivary-glands, lined by a single layer of some-what cylindrical cells, with a more or lessconical apex towards the very narrow lumen ofthe acini. [As in the salivary glands, thereis a narrow intermediary part of the ductsopening into the acini, and lined by flattenedepithelium]. The cells lining the acini consistof two zones (Fig. 139) :— (1.) The smaller parietal layer (outer) is transparent, homogeneous,sometimes faintly striated, and readily stained with carmine and log- 22. Fig. 139.

It undoubtedly con-tributes to the secretion by giving off material, the granules beingdissolved, and this zone becoming smaller (Heidenhain). The spherical
