MBBS QUESTION #10211
Question 1
The medulla of the adrenal (suprarenal) gland is embryologically derived from which tissue, explaining its function as a modified sympathetic structure secreting catecholamines?
  • Neural crest cells✔️
  • Coelomic mesothelium (intermediate mesoderm)
  • Endoderm of the primitive gut
  • Surface ectoderm
Correct Answer Explanation
The adrenal medulla develops from neural crest cells that migrate to the developing adrenal cortex (itself of mesodermal/coelomic epithelial origin) and differentiate into chromaffin cells — essentially a specialized sympathetic ganglion secreting catecholamines directly into the bloodstream.
