Adrenal Medulla Development This animation shows the dual embryonic origins of the adrenal development. Adrenal Cortex
Adrenal Medulla
|
- Fetal Adrenals - fetal cortex later replaced by adult cortex
- Week 6 - fetal cortex, from mesothelium adjacent to dorsal mesentery; Medulla, neural crest cells from adjacent sympathetic ganglia
- Adult cortex - mesothelium mesenchyme encloses fetal cortex
