What is Simbryo? Simbryo is a unique, comprehensive web-based center of animated embryological processes. It offers high quality, original vector art animations depicting some of the most difficult embryological developments using Flash. The seven Simbryo modules of normal development, including Early Development, Cardiovascular, Genitourinary, Gastrointestinal, Pulmonary, Head and Neck, and Limbs, present a systems-based approach to embryology. Select cardiovascular, neural tube, and limb defects are depicted as well. There are two versions, lecture and full, making Simbryo a useful teaching aid in class or as a stand alone tutorial for students.
