  • The embryos growth centers around the axis,
    which will become the spine and spinal cord.

Week 5-6
  • Chemicals produced by the embryo stop the womens
    menstrual cycle.
  • Brain activity is shown at the 6th week.
  • The heart will begin to beat around the same
  • Limb buds appear where the arms and legs will
  • Organogenesis begins.
  • The head represents about one half of the
    embryos axial length.

Week 7-8
  • The embryos blood type becomes apparent.
  • The embryo is capable of motion.
  • The eyes begin to form.
  • Organogenesis and growth continue.
  • At the end of the 8th week, the embryonic stage
    is over and the fetal stage begins.

8th Week
  • All major structures are shown, including the
    hands, feet, head, brain, and other organs are
    present but they continue to grow and develop.
  • The fetus is about 1.2 inches in length and the

  • More muscle tissue and bones have developed.

16-25 Weeks
  • Eyebrows, eyelashes, fingernails, and toenails

26-38 Weeks
  • Fingernails begin to reach the end of the
  • Small breast buds are present on both sexes.
  • Head hair becomes more thicker.
  • The fetus is considered full-term by week 35.
