  1. 1What is the name of the earliest known work in which the Church proclaimed the sanctity of human life? When was this written?The earliest known work in which the Church proclaimed the sanctity of human life was the Didache in 90 AD.
  2. 2The Fathers of the Church who defended the sanctity of human life included Saint....Athenagoras, Saint Basil the Great, Saint Jerome, and Tertullian.
  3. 3The major way in which the baby is different from the mother is......“every cell in the baby differs from every cell in the mother.” Two other ways the baby can be different from the mother are: the baby’s blood type, and half the time the baby’s gender is different.
  4. 4Which person is in charge of the pregnancy of a mother?The fetus is in charge of the pregnancy of a mother.
  5. 5chromosome..is a molecule that contains one or more of the traits or characteristics for the child.
  6. 6A gene...is a specific portion of the complex DNA molecule, which codes for one kind of protein.
  7. 7process in which the zygote begins to grow and divideMitosis
  8. 8cell division in which the cells divide into smaller cells rather than same-sized cellsCleavage
  9. 9Un óvulo fertilizado contiene 46cromosomas, 23 del padre y 23 de la madre.
  10. 10genomeThis is the term for the genetic code or the hereditary information that is contained within the DNA.
  11. 11Egg and sperm cells have ......a unique capability to create a new cell with a new chromosomal makeup.The egg and sperm cells each contain only twenty-three chromosomes, while other, normal, cells have a complete set of forty-six chromosomes.
  12. 12Chromosomes reside inthe DNA in the nucleus of egg and sperm cells, and provide the chemical instructions for human development
  13. 13The transmission of traits from the parent to the child is called ...Heredity
  14. 14Who was Dr. Jerome Lejeune ?Was a French geneticist and professor of genetics at a university in Paris.
  15. 15The development of the child can be broken down into four interdependent parts: growth, morphogenesis [mor-fō-jen-ĭ-sis], determination, and differentiation.1) growth.
    2)morphogenesis.
    3)determination.
    4)differentiation.
  16. 16Growthrefers to an increase in size
  17. 17MorphogenesisIs the origin of form or shape such as the appearance of fingers and toes.
  18. 18Determinationalso called restriction, means that a part of the embryo becomes restricted to a specific role or function.
  19. 19DifferentiationDetermination, also called is a process whereby cells become specialized and the appearance of a new property emerges such as muscle cells beginning to contract.
  20. 20What is fertilization?Fertilization, or conception, is the process whereby a living sperm cell and a living egg cell fuse to form a new, distinct, single-celled living person.
  21. 21The Period of the Embryo lasts..from day one until the eighth week. The Period of the Fetus lasts from the ninth week until birth.
  22. 22The difference between the ovum and the zygote is...the zygote is a fertilized ovum. The ovum, or egg, has 23 chromosomes, while the zygote has 46.
  23. 23the process in which the living fertilized egg divides into two smaller cells.Cleavage
  24. 24Blastomeres are ......all of the cells that result from the early cleavage stage.
  25. 25A morula .....is a zygote that has become a solid ball of blastomeres, after about 3 days. It is called a blastocyst when the morula hollows out in the center and fills with fluid.
  26. 26Trophoblastsare cells that form the outer, protective layer of a blastocyst.
  27. 27The fallopian tubeThe fallopian tube, or uterine tube, is where the blastocyst slowly passes down until it reaches its place of rest called uterus or womb
  28. 28Nutrients in “uterine milk”Uterine milk contains glycogen, proteins, lipids, and some essential minerals.
  29. 29Implantation of the blastocyst within the uterus occurs....around six days following fertilization.
  30. 30The period of the embryo...includes ✔development of the placenta ✔ the formation of the primary internal organs ✔the appearance of the baby’s major external body structures.
  31. 31The placenta is the organ that...attaches the unborn child to the uterine wall of the mother. The placenta serves as a liver, kidney, and lung for the embryo. It is also responsible for the production of fetal hormones, and provides nutrients from the mother to the developing baby.
  32. 32is a hormone that plays a role in maintaining the pregnancy.Progesterone
  33. 33are finger-like projections that form fetal capillaries that contain fetal blood.Chorionic villi
  34. 34Passive immunityhelps protect the child from many infections during the first few months of its life.
  35. 35... is the random movement of molecules from an area of higher concentration to an area of lower concentration.Diffusion
  36. 36Lacuaneare sacs that surround the chorionic villi. The lacunae contain nutrients and carry oxygen from the mother’s blood that diffuse across the thin membrane of the chorionic villi to assist with nourishment.
  37. 37Passive immunitywhich is built up by the mother during pregnancy, can be passed through the placenta to the child and will remain with the baby for up to six months following birth.
  38. 38Las tres capas germinales de un niño en desarrollo sonEctodermo, Mesodermo y Endodermo
  39. 39The Ectodermis the first and outer germ layer which becomes skin, hair, nervous system
  40. 40The Mesodermis the middle germ layer, becomes the skeletal system, muscular system, circulatory system, and urinary system.
  41. 41The Endodermthe inner layer, forms the digestive tract and some internal organs including the liver, pancreas, and thyroid.
  42. 42At the end of the third week, the embryo...is about as long as the thickness of a nickel and weighs about one gram.
  43. 43fourth weekDuring the process of organogenesis, the rudimentary organs that develop are: the thyroid gland, lungs, liver, pancreas, and kidneys.
  44. 44Spina Bifidais a defect of the spinal cord where part of the spinal cord may stick out through an opening in the vertebra. Spina Bifida can be caused by a lack of B vitamins, especially folic acid.
  45. 45the fifth to seventh weeks 7 Wthere are many the features that develop. These include a brain, blood flowing through its vessels, and the head grows rapidly and becomes round. The eyes, nose, and mouth develop and form the face of the baby. All of the twenty milk teeth buds are present. The arms and legs are no longer buds but limbs, and fingers and toes emerge. All of the major organs have formed and continue to grow.
  46. 46second month 2 Membryonic bone formation has begun in the unborn and the bones are very elastic, and remain cartilaginous until the sixth month.
  47. 47The chorion membranedevelops from the trophoblast, and surrounds the embryo and will form a part of the placenta. The amniotic membrane forms a protective layer around the embryo and forms the amniotic cavity which will contain the amniotic fluid.
  48. 48second month 2 Membryonic bone formation has begun in the unborn and the bones are very elastic, and remain cartilaginous until the sixth month.
  49. 49The chorion membranedevelops from the trophoblast, and surrounds the embryo and will form a part of the placenta. The amniotic membrane forms a protective layer around the embryo and forms the amniotic cavity which will contain the amniotic fluid.
  50. 50Three important functions of the yolk sacare: It forms blood cells in the early stages of development, provides circulation until the circulatory system develops, and it gives rise to germ cells.
  51. 51propósitos del líquido amnióticoson la protección, la amortiguación y la regulación de la temperatura.
  52. 52Fetus is a Latin word meaning “young one.”The unborn baby is called a fetus beginning with the ninth week.
  53. 53third month 3 Mthe neck elongates and straightens, the eyelids grow over the eyes, and fingernail and toenail growth begins.
  54. 54The placenta and the umbilical cord.The unborn receives nutrients from the placenta through the umbilical cord. Oxygenated blood is also provided in this way.
  55. 553MThe bones of the unborn begin to harden in the third mont.
  56. 56LanugoThe hair-like coating that covers the unborn baby at four months is called lanugo.
