Fetal Development
Immediately upon fertilization,
cellular development begins. Even before implantation,
the sex of the new life can be determined, and the blueprint
is in place for every detail such as hair and eye color, height,
and skin tone.
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. This happens during days 5-9.
During days 17, 18, 19
the new life has developed
its own blood cells. The placenta is a part of the new
life and not of the mother. On occasion, pulsations begin
in the muscle that will be the baby's heart. The eyes
start to develop.
At day 20 the foundation of the
entire nervous system has been laid down.
From Day 24-30 40 pairs of muscles, which
will be the arms and legs, develop along the trunk of the new
life. Regular blood flow begins within the vascular system,
and the ears and nose begin to develop.
From Day 40-49 the heart energy output
is reported to be almost 20% of the output of an adult. About
the time most mothers learn they are pregnant, the skeleton
is complete and reflexes are present. Electrical brain wave
patterns can be recorded. There is ample evidence that thinking
is taking place in the brain. The new life
is now a thinking person and is complete with fingers, toes,
and ears.
At Day 56 all organs are functioning
- stomach, liver, kidneys, brain - and all systems are intact.
This new life has all of his/her parts, even lines in the palms
of their hands.
In the 9th and 10th weeks
the child squints, swallows
and retracts his/her tongue.
In the 11th and 12th weeks
the arms and legs move.
The baby sucks his/her thumb, inhales and exhales amniotic fluid.
The nails appear.
At 16 weeks (4 months)
the genital organs are
clearly differentiated. The baby grasps with its hands, swims,
kicks, and turns somersaults.
At 18 weeks the baby can cry!
At 20 weeks the baby has hair! The
baby weighs about one pound and is 12 inches long.
