The study of embryology can present difficulties for many students. This colouring book, the only one available that deals solely with embryology, will help overcome these difficulties that students face. In over 300 pages of detailed, clearly labelled line diagrams, it covers all stages of human embryo development. Each set of illustrations has a companion text which provides the essential information on embryology for the student. This is truly a one of a kind book and quickly becoming very difficult to acquire. In fact, the only one I have been able to find online is via amazon and priced at over $600. Once these are gone they will likely not be available in the future.
