Document Summary

Working the scientific model: migration of the blastocyst from the fallopian tubes and its implantation in the uterus, cellular divisions take place that eventually lead to multiple organ, nervous system, and skin tissues, stage in which basic cell layers become differentiated, major structures such as the head, heart, limbs, hands, and feet emerge, embryo attaches to the placenta, brain development progresses as distinct regions take form, circulatory, respiratory, digestive, and other bodily systems develop, sex organs appear at around the third month of gestation. The moro reflex noises: helps the infant begin feeding immediately after birth, the moro/startle reflex occurs when infants lose support of their head. Infants grimace and reach arms outward and then inward in hugging motion: may be a protective reflex that allows infant to hold on to the mother when support is suddenly lost, elicited by stimulating the infant"s palm.
