Answer

  1. Neuron

Explanation:

The nervous system develops at an amazing rate after embryogenesis, at times adding 250,000 neurons every minute. At birth, almost all neurons that the brain will ever have are present. However, the brain continues to grow for a few years after birth with the help of glial cells. By the age of 2 years old, the brain is about 80% of the adult size.
