Chapter 1 Introduction

Play Movie Play Movie	The dynamic process by which the single-cell human zygote becomes a 100-trillion-cell adult is perhaps the most remarkable phenomenon in all of nature.
Play Movie	Researchers now know that many of the routine functions performed by the adult body become established during pregnancy - often long before birth.
Play Movie \| See Snapshots	The developmental period before birth is increasingly understood as a time of preparation during which the developing human acquires the many structures, and practices the many skills, needed for survival after birth.
Chapter 2 Terminology

Play Movie	Pregnancy in humans normally lasts approximately 38 weeks as measured from the time of fertilization, or conception, until birth.
Play Movie \| See Snapshots	During the first 8 weeks following fertilization, the developing human is called an embryo, which means "growing within." This time, called the embryonic period, is characterized by the formation of most major body systems.
Play Movie \| See Snapshots	From the completion of 8 weeks until the end of pregnancy, "the developing human is called a fetus," which means "unborn offspring." During this time, called the fetal period, the body grows larger and its systems begin to function.
Play Movie	All embryonic and fetal ages in this program refer to the time since fertilization.
