## Abstract The first stage in the formation of the liver is two ventrolateral evaginations of the midβgut at the time of hatching. From the undifferentiated cells branching from the liver duct the pancreas cells arise, but do not assume adult character until the carp is about 41 mm. long. The isl
Studies of pancreatic development have suggested that the islet cells develop through multihormonal stages. Abundant data have confirmed that multihormonal cells are common during pancreatic development. A number of transcription factors and homeotic proteins have also been found to be important to
Electromyograms (EMG's ) of developing chick embryos were recorded with an electrolytically sharpened tungsten electrode and with a concentric unipolar electrode. Earlier observations of the occurrence of movements on the sixth day were confirmed. Before the twelfth day, only small irregular potent
In the literature, some controversy still exists about the normal and abnormal development of the human anorectum. Therefore, a threedimensional and histological study was performed on human embryos. In early anorectal development (Υ 49 days postfertilization), the cloaca plays a crucial role, separa
