The epithelium is not the same in the two kinds of glands : the mucous glands (Fig. 189, a, 6) are lined with cylinder-epithelium throughout their extent; the peptic glands (Figs. 187,188) are lined with cylinder-epithelium at their origin (Fig. 187, a), but the secretory tubes contain round peptic cells. (Each caeca, when highly magnified, is found to consist of a delicate basement membrane (Fig. 188, a) inflected over a series of nearly globular cells (h), which occupy almost the whole cavity . of the tube, and contain a finely-granular matter; the narrow passage left vacant in the centre is, however, still surrounded by a layer of epithelial cells (c), whose small size is in striking contrast to the large dimensions of the gland cells.) The muscular layer (of the mucous membrane) is immediately beneath the glandular structure, and contains two planes of intersecting fibres. Lastly, the connective layer of the corium is thick and loose, sustains the vessels (and nerves), and unites the mucous to the muscular tunic of the stomach. 4. Vessels and nerves.âThe stomach receives its blood by the two branches of the gastric artery, the splenic and its terminal branchâthe left epiploic artery, and by the pyloric and right epiploic arteries.
