    wound healing; over-exuberant physiological response; uncontrolled growth
  5. Investigation of developmental disease.
  6. What does "ontogeny recapitulates phylogeny" mean?
    Development of an individual will parallel the development of the species
  7. Damage in the first trimester (embryo) usually results in... (3)
    abortion, resorption, and need for repeat breeding
  8. Damage during the second trimester (fetus) usually results in... (2)
    fetal abnormalities, in utero death with mummification
  9. Damage during the third trimester usually results in... (3)
    minimal effects, perhaps born dead, too weak to suckle
  10. Developmental defects are often ___________ or __________.
    inherited; acquired in utero
  11. Inherited developmental defects commonly manifest as... (3)
    predispositions to drug reactions, higher susceptibility to infectious diseases, and heightened incidence of some neoplasms.
  12. Stage of emryogenesis when the conceptuses begin their transformation into trilaminar embryos.
  13. Common causes of developmental defects acquired in utero. (5)
    deficiencies, infections, mechanical injury, radiation, xenobiotics
  14. Complete failure of an organ or tissue to develop.
  15. Failure to form a complete internal lumenal structure.
  16. A developmental condition in which the tissue elements are normal but the histologic structure is disorganized and therefore not functional.
  17. Failure of cell populations to their proper locations.
  18. Failed fusion of midline structure.
  19. Failure of an organ to achieve full adult size, but otherwise normal histologically.
  20. Formation of novel structures.
    "new organs"
  21. Epithelial lining of GI (except mouth, pharynx, and anus), respiratory tract, thyroid follicles, urinary bladder, and urethra form from the ____________.
  22. The notochord forms from the __________ of the ___________.
    chorda; mesoderm
  23. The kidneys and gonads form from the ____________ of the ____________.
    intermediate; mesoderm
  24. The circulatory system, fat, and muscles form from the _____________ of the ___________.
    lateral plate; mesoderm
  25. The dermis, bone, and cartilage form from the ____________ of the ____________.
    paraxial; mesoderm
  26. The adrenal medulla, melanocytes, peripheral NS, dentin of teeth, and facial cartilage form from the _____________ of the _____________.
    neural crest; ectoderm
  27. The CNS and retina form from the ____________ of the ___________.
    neural tube; ectoderm
  28. The cornea, skin, and enamel of teeth develop from the _____________ of the _____________.
    surface; ectoderm
  29. Type of placentation with many discrete zones connecting the fetal chorioallantois and adjacent endometrium (caruncle); what type of animal does this occur in?
    cotyledonary; ruminants
  30. Type of placentation where nearly the entire chorioallantois surface aids in fetal/maternal interactions; what kind of animal does this occur in?
    diffuse; horses, pigs
  31. Type of placentation where attachment is at a complete or incomplete band encircling the fetus; what kind of animal does this occur in?
    zonary; carnivores
  32. Type of placentation where there is one large placental disc that caps the other embryonic membranes; what kind of animal does this occur in?
    discoid; rodents, primates
