216 Days To Go
The surface of the baby's brain is now beginning to develop the rounds and fissures characteristic of humans. The upper lip is fully formed. Primary ossification centers are appearing in the long bones. These centers direct the replacement of cartilage by bone. The ossification process always starts in the upper arms, where the first true bone cells will replace the cartilage. If our baby is a girl, the clitoris is beginning to form from the same tissue that the penis, if a boy, will develop from. By this time, the critical period for the baby's heart development has ended. The heart will continue to grow and develop, but not at such a fast pace.
