A manual of human physiology, including histology and microscopical anatomy, with special reference to the requirements of practical medicine . lium is sharply defined atthe cardia from the stratified epithelium of the oesophagus, and also atthe pylorus, from the true cylindrical epithelium with the striated disc inthe duodenum. [The cells in the passive condition seem to consist oftwo zones, an outer clear part, next the lumen of the organ, consistingof a substance (mucigen) whichyields mucus, the attached endof the cell being granular.]The oval nucleus lies about thecentre of the cells. Spindle-shaped, nucleated cells, probablyfor replacing the others, are saidby Ebstein to occur at theirbases. All the cells are open attheir free-ends, so that the mucusis readily discharged, leaving thecells empty (F. E. Schultze).Numerous tubular glands of twodistinct kinds are placed ver-tically, like rows of test-tubes, inthe mucous membrane. Fundus-glands.—On making avertical section of the cardiacportion of the gastric mucousmembrane, and submitting it tomicroscopic examination, it is seen to consist of a number of tubular glands 21i.

These are the fundus-glands (Heidenhain), otherwisecalled peptic, or cardiac. Several gland-tubes, which are wider below,usually open into the short duct (Fig. 136). Each gland consists of astructureless membrana propria with anastomosing branched cells inrelation with it. The duct is lined by a layer of cells like those liningthe stomach, while the secretory part of the tubes is lined throughoutby a layer of granular, short, small, polyhedral, or columnar nucleatedcells. These cells border the very narrow lumen, and were calledchief or principal cells by Heideuhain; they are also known as centralcells (Fig. 134, II, a), or adelomorphous (aSrjXoc, hidd
