Abstract :

Histogenesis of Suprarenal Gland in Fetuses of Different Gestational Ages. A total of sixty foetal suprarenal glands (right and left) from 9 to 36 weeks were studied to note the histological changes using routine histological staining procedures The study also includes the migration patterns of neuroblastic nodules through cortex to medulla of suprarenal gland at different gestational ages. Three distinct zones could be identified foetal transitional and definative zone. The arrangement of cells in definitive cortex changed from the discrete cells and clustures to well formed gomerulus like structure. Neuroblastic cells migrates from capsule towards central blood vessels. They differentiate into the chromaffin cells and sympathetic neurons, decreasing the number of neuroblastic nodules from 20 week onwards.
