This Week in Flappy's Proto-Humanhood

Week 19

The dude/tte is pooping. So that's interesting.

After about 16 weeks the kid is swallowing amniotic fluid. Technically it is called meconium but if a greenish-black tarry excretion comes out of your kid's backside, it is poop no matter where they are.



For the topic of this blog here the big exciting activity is myelination of the spinal cord. Myelin is like that rubber coating on a wire. It keeps electrical activity where it belongs and speeds it along.



Multiple sclerosis attacks the cells that make the myelin. You lose that little bit of infrastructure, the wiring insulation, and you aren't you anymore except in the least important ways.
