. The comparative anatomy of the domesticated animals. Veterinary anatomy. THE DIGESTIVE APPARATUS IN epithelium throughout their extent; the peptic glands (Figs. 263, 204) are lined with cylinder-epithelium at their origin (Fig. 263, a), but the secretory tubes contain round peptic cells. (Each caeca, when highly magnified, is found to consist of a delicate basement membrane (Fig. 265, a) inflected over a series of nearly globular cells (b), 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), the small size of which 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 con- tains two planes of intersecting fibres. Lastly, the con- nective tissue 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 sple7iic and its terminal branchâthe left epiploic artery, and by the pyloric and right epiploic arteries. The principal arterial ramifications extend between the mucous and muscular layers, where they furnish two capillary reticulations to the glandular layerâa deep network that sun-ounds the secretory tubes, and a superficial placed between the alveoli. The blood is carried from the organ to the vena portae by the satellite venous branches. The MUCOUS GASTRIC GLAND WITH lymphatics form a subserous and two deep networks at CYLINDER EPITHELIUM. ,, i /â .1 i j i i 3 â .^ n-, , , , . the base of the glandular layer and m the fibrous mem- ^' ' * appendage.'' ^ ^^^^ brane.
