◦ developmental programming
◦ small-for-date
◦ errors of metabolism
◦ calorie restriction
Question 2
Which of the following is a reason the embryonic period is the most vulnerable period of development?
◦ Nearly two-thirds of embryos fail to complete development, resulting in miscarriages.
◦ Brain development is nearly complete by the end of the embryonic period and thus vulnerable only at this time.
◦ It is when all of the major organs and body parts develop in rudimentary form and are potentially sensitive to environmental toxins.
◦ The embryo is small and weak and unable to resist toxins in the mother's body.
