4D Ultrasound – Pre-born Baby At 16 Weeks
Watch this 4D Ultrasound video of a child at 16 weeks:
Here are some facts about a fetus:
- By Day 15, the fetus begins developing neurons in the brain and spinal column.
- By Day 22, the heart begins to beat.
- Up to the age of 8 weeks, the fetus subsists on the yolk sac, which then shrivels away as the fetus begins to rely on his mother for continued nourishment.
- At 9 weeks, reflexive movement meant to strengthen and exercise his body begins.
- At just 11 weeks, the fetus exercises the sucking reflex he will need to feed at birth, and develops left or right-handedness at this time – not in childhood, as originally thought.
- By 16 weeks, the nervous system is up and running, and his bones begin to harden.
- By 16 weeks, the fetus squirms when prodded.
- By 16 weeks, the fetus is aware of his environment, especially sounds, since hearing is the first sense to develop. He is especially sensitive to his mother’s voice, and can recognize music – he has memory.
Experts agree that there is no difference between the 33-week old fetus and the newborn child. In fact, birth could be a relatively insignificant event in developmental terms.
