Moreover the tendency of the mesoderm to grow ventrally around the archenteron is visible. Note also the different aspects of the mesodermal cell types. The medial, myogenic cells have a soinewhat club shaped appea- rance in cross sections, with their narrow ends pointing towards the neural tube. The late- ral cells display a flatter, epithelial character. As they border the extensive coelomic cavity laterally they are tenned coelothelial cells. The ventrolateral area of the neural tube shows cross sections of Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Bonn, Zoologisches Forschungsinstitut und Museum Alexander Koenig
