Plate 1 Fetal Gall Bladder

1 Gall bladder and duodenum of a 40 mm human embryo; cross section at the level of the umbilicus. The cells of the endodermal epithelial lining appear uniform in size and staining reaction. The mesodermal portion of the gall bladder shows only a slight indication of differentiation into layers. The passage through the duodenal wall of the ductus choledochus and the ductus pancreaticus is seen. Photomicrograph, X 50.

2 Gall bladder of an 80 mm human embryo; cross sections from the corpus (a.) and from the neck (b). The alveolar indentations and corresponding round elevations give a pattern to the mucosal surface. This is particularly marked in the neck, where the stellate lumen is composed of several communicating epithelial-lined indentations. The muscular coat is a well-defined layer of smooth-muscle cells embedded in a connective-tissue stroma. Photomicrographs, X 60.
