Presentation Transcript

  1. Prenatal Development

  2. Sperm: The male sex cell • Ovum: The female sex cell

  3. Conception • The union of an ovum (egg) and a sperm, resulting in the beginning of pregnancy. • www.teenwire.com (Prevention)

  4. www.teenwire.com Fallopian Tubes: Where conception usually takes place • Ovary: • Releases the egg

  5. Where does conception usually take place? In the fallopian tubes

  6. Where does the fertilized egg implant? • In the uterus.

  7. Vagina: • The opening to the reproductive organs • Passageway through which menstrual flow leaves the body

  8. Pap Smear: Test for cervical cancer

  9. Obstetrician • A doctor that specializes in the care of pregnant women.

  10. Prenatal Period • The time from conception to birth

  11. The First Trimester of Pregnancy • Most miscarriages are likely to occur at this time

  12. Miscarriage • The natural ending of a pregnancy before the fetus could survive.

  13. Stillbirth • The natural ending of a pregnancy after 20 weeks • this happens by accident and is not the fault of the father or mother

  14. Ectopic Pregnancy • (Tubal Pregnancy) • When a fertilized egg implants in the fallopian tubes.

  15. Embryo • The developing cluster of cells from the third to the eighth week of pregnancy.

  16. What is a congenital problem? • a physical or biochemical problem in a baby that is present at birth. • Down Syndrome • Cleft Lip • Muscular Dystrophy • Cerebral Palsy

  17. What causes congenital problems? • Environmental causes • nutritional balance of mother’s diet • any disease or infections the mother may have during pregnancy • harmful substances • outside hazards (radiation) • Heredity • Errors in chromosomes

  18. Fetal Alcohol Syndrome • 3/1,000 babies have FAS • Mother drinks heavily during pregnancy • alcohol interferes with brain development • heart defects • poor motor development FAS Brain Normal Brain

  19. The Second Trimester of pregnancy • Movement of the fetus is felt by the mother.

  20. Fetus: • The unborn baby from about the eighth or ninth week till birth.

  21. Ultrasound: • To evaluate the growth & development of the fetus. • A technique using sound waves to make a video image of an unborn baby

  22. Primary purpose of an ultra sound? • To check for health problems and fetal development • Skeletal/ organ defects

  23. Amniocentesis • The withdraw a sample of the amniotic fluid surround an unborn baby with special needle and testing for fluid for indications of specific birth defects or other health problems

  24. Rh Factor • Protein substance found in the red blood cells of 85 % • Causes a problem to the baby when the father is Rh+ and the mother is RH- Rh Disease: type of anemia that destroys the baby’s red blood cells

  25. Iron • Needs more iron than usual to produce all the blood needed to supply nutrition to the placenta

  26. FOLIC ACID • Aids in the creation of the baby's nervous system. • Folic acid can help prevent congenital defects such as, spina bifida, cleft palate or cleft lip.

  27. Weight Gain for Mom • Suggest between 25-30 lbs • Eat an extra 300 calories per day • Much of the weight gain goes to the growing baby and the tissues that support it

  28. Physical Activity • Should be active unless told otherwise from her doctor • Avoid contact sports • Helps keep weight within normal activity, strengthens muscles used during birth, increases energy

  29. STOP!!! • We are going to switch gears now and move on to look at fetal development in more detail.

  30. The Third Trimester of Pregnancy • If born, the baby has the greatest chance of survival. • The fetus assumes the birth position. • The unborn fetus grows ½ pound per week. • The unborn child develops protective immunities.

  31. 3 Stages of Labor • 1st Stage: • Contractions begin • Cervix dilates • 2nd Stage: • Child birth • 3rd Stage: • Placenta is expelled

  32. Lightening: • The term that best describes the baby dropping in to the birth position.

  33. Amniotic Fluid • Acts as a shock absorber for the fetus.

  34. Show • vaginal discharge prior to the beginning of birth • mucus plug is released from the cervix • brownish or blood tinged • labor will begin in 3 days

  35. Contraction: • The tightening and releasing of uterine muscles.

  36. Dilation: The widening of the cervix Effacement:The thinning of the cervix

  37. Cervix: • The lower part of the uterus

  38. Labor • The process by which the baby gradually moves out of the uterus.

  39. Breech Birth: • When the baby is born feet or buttocks first.

  40. Caesarean: • (C-section) baby born by surgical opening in the uterus.

  41. Crowning • Appearance of the head during delivery
