1. The adrenal medulla stems from embryonic neuro-ectoderm. 2. Comprising rounded clusters of large granular cells known as chromaffin cells, it consists of modified post-ganglionic cells from the sympathetic nervous system. 3. These cells maintain connections with preganglionic fibers of the sympathetic nervous system. 4. Consequently, the adrenal medulla serves as a continuation of the … Read more
