| Description | Fig. 351.—Transverse sections of embryo of Ascaris megalocephala, in order to show the invagination of the anterior mesoderm cells and of the mother cells of the genital organs. (After Boveri.) A, section of a stage in which the endoderm cells are invaginated, but in which the mesoderm cells are still superficial. B, section of a stage in which the mesoderm cells have passed into the blastocoelic cavity. C, section of a stage in which the genital cells are beginning to be invaginated. D, section of a stage in which the invagination of the genital cells is complete. |
