- Immediately upon fertilization, cellular development begins. Before
implantation the sex of the new life can be determined.
- At implantation, the new life is composed of hundreds of cells and has
developed a protective hormone to prevent the mother's body from rejecting
it as a foreign tissue.
- At 17 days, the new life has developed its own blood cells; the placenta
is a part of the new life and not of the mother.
- At 18 days, occasional pulsations of a muscle - this will be the heart.
- At 19 days, the eyes start to develop.
- At 20 days, the foundation of the entire nervous system has been laid
- At 24 days, the heart has regular beats or pulsations.
- At 28 days, 40 pairs of muscles are developed along the trunk of the new
life; arms and legs forming.
- At 30 days, regular blood flow within the vascular system; the ears and
nasal development have begun.
- At 40 days, the heart energy output is reported to be almost 20% of an
- At 42 days, skeleton complete and the reflexes are present.
- At 43 days, electrical brain wave patterns can be recorded. This is
usually ample evidence that "thinking" is taking place in the brain. The new
life may be thought of as a thinking person.
- At 49 days, the baby has the appearance of a miniature doll with complete
fingers, toes and ears.
- NAME CHANGED FROM EMBRYO TO FETUS. At 56 days all organs functioning -
stomach, liver, kidney, brain - all systems intact. Lines in palms. All
future development of new life is simply that of refinement and increase in
size until maturity at approximately age 23 years. This is approximately two
months before "quickening" yet there is a new life with all of its parts
needing only nourishment. The mother will usually not feel the child's
movements until four months after conception.
- 9th & 10th week, squints, swallows, retracts tongue.
- 11th & 12th week, arms & legs move, sucks thumb, inhales and exhales
amniotic fluid, nails appearing.
- 16 weeks (four months), genital organs clearly differentiated, grasps with
hands, swims, kicks and turns somersaults (still not felt by mother).
- 18 weeks, vocal cords working . . . can cry.
- 20 weeks, hair appears on head; weight - one pound; height - 12 inches. A
fetus (little one, child, baby) is essentially no different at
fertilization, ten weeks, twenty weeks or thirty weeks. A person is a
person, no matter how small.
