PSYCH 111 Lecture Notes - Lecture 11: Plantar Reflex, Prenatal Development, Birth Weight
Document Summary
There are certain aspects of development that stay the same. 3 stages in prenatal development: germinal phase. During the stage of fertilization, you see the development of the placenta. Use of the placenta has some cultural variation; in some cultures it is thrown out, ate, or planted to grow a tree s5. There are many things happening during the fetal stage (only some are shown here) Here it is considered a fetus, no longer an embryo. Some antibiotics can affect the coloring of the teeth. At this point, you can see if it is going to be a male or female s6. Lanugo: believe that this is used a source of protection. Vernix: used for protection and as a lubricant to help the baby come out s7. Your birth weight is not the weight you leave the hospital with; generally the babies will lose some weight by the time they leave.
