The book "Your Body, How it works: Human Development" by Ted Zerucha is very informative about exactly what happens in pregnancy from the pre-zygotic (before fertilization) stage to the final stage. Basically, it talks about the cells and how they replicate/arrange themselves in order to form a baby. In the beginning of the book it is described how humans can cause/prevent themselves from becomming unhealthy, and basically what development even is and how early humans thought they came about. As the book proceeds to the middle, it explains the specific stages of pregnancy and how delicate the process is. In chapter 4, it describes how a human starts off as one single cell, then how it replicates into multicellularity. Once the higher chapters are reached, the book gets into the developing embryo in the embryonic stage, and talks about how the sells undergo specific movements as they rearrange themselves in a process called gastrulation. Proceeding into chapter 6 the book describes in great detail about the formation and function of the neural tube. Also, it introduces the function of hox genes, which are described in the next chaper. Chapter 7 teaches about how hox genes are organized and where they are. Finally, in chapter 8, the last chapter in the book, it talks about hte development of limbs. Limbs are organs and so in this stage of development a humans organs are also being developed, a process known as oranogenesis. Once this stage is complete, the fetus has the characteristics of a human baby. In conclusion, this is a great book to read for those who are interested in genetics, or even anatomy and physiology.Was this review helpful? Yes NoThank you for your feedback.
