236 Days To Go
By this time, thirty-eight pairs of somites have formed. (the somites form the bones and muscles of the head and trunk. Don't worry, I had to look it up too) If they haven't appeared already, the leg buds will be present today.
The baby's brain has differentiated into the three main parts possessed by all human brains: the forebrain, the midbrain, and the hindbrain.
- The hindbrain contains regions that help regulate heart rate and breathing and coordinate muscle movements
- The midbrain is a relay station, sending messages to their final destinations in the brain
- The forebrain has specialized structures called "lobes" that translate input from the senses, play a role in memory formation and storage, and engage in "higher order" processing, like thinking, reasoning, and problem solving.
The baby now measures ¼ inch (6-7mm) long - that is 10,000 times bigger than at conception, and we are only at day 30!
