    Exit passageway to the outside of the mother's body.
  6. Blastula
    Ball-like mass of cells in the embryonic period with fluid-filled (amniotic fluid) center.
  7. Childhood Period
    child - One year to puberty
  8. Chorion
    Embryonic/Fetal membrane that surrounds the amnion.
  9. Chromosomes
    Structures in the nucleus of a cell that contain the genes (responsible for heredity) for genetic expression.
  10. DNA
    Deoxyribonucleic acid, the molecular basis for heredity, it is present in chromosomes.
  11. Dominant Gene
    A gene that produces a recognizable effect in the organism.
  12. Ectoderm
    External primary germ layer, gives rise to: Nervous Tissue, Epidermis & its appendages, & Linings of mouth and anal canal.
  13. Ectopic Pregnancy
    • (Tubal Pregnancy is an example) -
    • Anytime a fertilized egg attempts to develop outside of the uterus.  Most common is a tubal pregnancy.
  14. Embryology
    Study of Human Anatomy before Birth.
  15. Embryonic Period
    Fertilization through 8th week (through the 2nd Lunar Month or 56th day).
  16. Endoderm
    • Internal primary germ layer, gives rise to: Epithelium of
    • Alimentary Canal/Digestive System (other than the mouth and anal canal), Respiratory System (other than nose), Urinary Bladder, & Urethra.
  17. Endometrium
    Mucous lining of the uterus, layer which thickens each month in anticipation of receiving fertilized egg.
  18. Fallopian Tube
    Uterine Tube
    Connects between the Ovary and the Uterus.  This is where fertilization generally takes place.
  19. Female Gamete
    Female sex cell, also called the egg, ova, ovum.
  20. Fertilization
    Union of the Sperm and the Egg.
  21. Fertilized Egg
    Zygote, after the sperm and the egg unite.
  22. Fetal Period
    From the 9th week (3rd Lunar Month or the 57th day) through Birth.
  23. Gastrula
    • Ball-like mass of cells in the embryonic period with hollow
    • center.
  24. Gene
    Portion of a DNA molecule, the hereditary unit occupying a fixed position in the chromosome; capable of reproducing itself at each cell division and of managing the formation of a protein.
  25. Gestation Period
    The time required for prenatal development.
  26. Heart Beats (Audible)  
    When the heartbeats can be heard with a stethoscope, during the fourth/fifth lunar month. (Fetal)
  27. Heart Beats (Inaudible)
    When the heart actually begins to beat, during the first lunar month of development. (Embryo)
  28. Implantation
    When the fertilized egg has attached itself to the wall of the uterus (endometrium).
  29. Infancy Period 
    - infant
    End of 4th week to one year.
  30. Intercourse
    When the father places the sperm in the mother’s body.
  31. Lanugo
    Fine downy-like hair on the fetus that begins to appear during the fifth month of prenatal development and begins to disappear before birth.
  32. Lunar Month
    28 Days or 4 Weeks (NOT a calendar month)
  33. Male Gamete
    Male sex cell, sperm, spermatozoa, spermatozoon, or "the seed".
  34. Menstrual Cycle
    • The sloughing off of the excess layers of the endometrium that has thickened in anticipation of the arrival of the fertilized egg, which never arrives.  Occurs approximately once every 28 days, with the beginning of puberty through menopause. 
    • The Menstrual Period.
  35. Mesoderm
    • the middle primary germ layer, gives rise to: 
    • Muscle Tissue, Connective Tissue (Cartilage, Bones, Lymph and Blood Cells), Epithelium of Blood Vessels, Lymph Vessels, Kidneys, Ureters, & Body Cavity Linings.
  36. Morula
    Mulberry-like mass of cells, the result of the early cell divisions of the zygote.
  37. Neonatal Period
    newborn - Birth through 4th week.
  38. Ova
    The female sex cell, the egg.
  39. Ovaries
    The female sex glands produce the eggs.
  40. Ovulation
    • The process of releasing an egg. 
    • Approximately once every 28 days.
  41. Placenta
    • The part of the embryonic mass that attaches itself to the
    • uterus (of the mother).
  42. Pregnancy
    When a woman is carrying a baby. (From Fertilization to Birth)
  43. Quickening
    The sudden active movements of the fetus (about the 5thn month).
  44. Recessive Gene
    • A gene that does not produce a recognizable effect in the
    • organism.
  45. RNA
    Ribonucleic acid, a component of all living cells, it carries the     information from the DNA to the protein forming areas of the cell.
