Fetal Development

As technology advances and gives us a better view inside the womb, scientists have been amazed to discover what actually happens during a pregnancy and how early in the pregnancy some developments occur.  We want to list a few of the more amazing findings.  (with footnotes)

1. Three weeks after conception the baby’s heart begins to beat and pump blood.(1)

2. At six weeks after conception, the baby has brain waves that can be measured with an electroencephalogram.(2)  According to the medical profession, life is defined as the presence of brain waves, and death as the cessation of brain waves.  According to this definition the fetus can be proven to be alive.

3. At seven weeks after conception, the baby begins swimming freely in the amniotic sac, though the mother is not aware of the movement until much later.(3)

4. At twelve weeks after conception, a baby has developed all the body parts required to experience pain, including all of the nerves, spinal cord, and thalamus.(4)
