Medulla
Neural crest cells migrate toward the coelomic cavity wall and form the adrenal medulla. These chromaffin (chromaphil) cells originally named because of their staining (yellow) with chromium salts.
Cortex
Week 4 celomic epithelium (mesothelium) cells proliferate initially forming small buds that separate from the epithelium.
Week 6 these now mesenchymal cells first form the fetal adrenal cortex which will be later replaced by the adult cortex.
