Suprarenal gland
 

 

The cortex of the suprarenal gland develops from the mesoderm while the medulla comes from neural crest cells. We first see the appearance of the cortex at about 6 weeks of gestation through aggregation of mesenchymal cells bilaterally placed between the root of the dorsal mesentery and the gonad. The mesodermal cells which form the cortex are derived from the mesothelium which lines the posterior abdominal wall. The medullary cells differentiate from neural crest cells which  migrate from adjacent sympathetic ganglion. The cortex then covers the medulla. The zonulation of the cortex begins in late fetal life and does not become evident until the 3rd year of life. It may develop congenital adrenal hyperplasia which may cause adrenogenital syndrome.
