Adrenal Medulla Development

This animation shows the dual embryonic origins of the adrenal development.

Adrenal Cortex

mesothelium origin, epithelium lining the body cavity at the site of adrenal development
Late Fetal Period - differentiates to form cortical zones
Birth - zona glomerulosa, zona fasiculata present
Year 3 - zona reticularis present

Adrenal Medulla

neural crest origin, migrate adjacent to coelomic cavity, initially uncapsulated and not surrounded by fetal cortex, cells have neuron-like morphology
2 cell types - secrete epinepherine (adrenaline) 80%; secrete norepinepherine (noradrenaline* 20%

-* 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
