This comprehensive, fully illustrated atlas features over 300 detailed, accurate, and fully labeled illustrations (photomicrographs, line drawings, and orientation drawings). It considers many different organisms, and features comparative embryology (i.e., gametogenesis in rat, human, cat, grasshopper, locust; development of Ascaris, sea urchin, starfish, frog, chick, and pig; and the human uterus and placenta). Comprehensive coverage of a large variety of developing organisms exposes readers to many different developmental strategies. Over 300 high-quality photo-micrographic illustrations enable readers to quickly identify similar structures in their own specimens using side-by-side reference to the atlas. Over 50 valuable line-drawings from classical textbooks present supplemental, interpretive views of photo-micrographic illustrations to help readers understand developmental events in four-dimensions i.e., the three dimensions of space, plus the dimensions of time. Combined glossary, synopsis of development and index are provided. For professionals in the field of biology."
