Plate 4 Fetal Gall Bladder

5 Gall bladder of a 370 mm fetus in longitudinal section. The active proliferation of the lining epithelium is rather conspicuous. Photomicrograph, X 120.

6 Gall bladder of a 280 mm fetus in cross section. The coarse ramifications (plexus perimuseularis) of the large vessels are located in the dense zone of the perimuseular layer, in that adjacent to the muscular coat. Branches of these vessels communicate through the muscular layer with the rich capillary bed (plexus subepithelialis) distributed beneath the lining epithelium. Photomier0graph, X 60.

7 The hepatocystic junction of the 40 mm human embryo. The lumen of the cystic duct merges gradually with that of the common hepatic duct. The endodermal portion of both duets is represented by a tube lined with a single row of columnar epithelial cells. The mosodermal portion is wholly undifferentiated. Photomicrograph, X 120.
