This stand-alone, comprehensive, fully-illustrated atlas of descriptive embryology features over 250 digitally-enhanced, detailed, accurate, and fully labeled illustrations (photomicrographs, line drawings, and orientation drawings). Offers comprehensive coverage of a large variety of organisms, explores many different developmental strategies, 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). Presents interpretive views of photomicrographic illustrations to help readers understand developmental events in four-dimensions (i.e., the three dimensions of space plus the dimension of time). Contains orientation drawings for transverse sections. Enables readers to quickly identify similar structures in their own specimens by side-by-side reference to the atlas. For those interested in comparative embryology/developmental biology.
