Question
Explain how the adrenal medulla and sympathetic nervous system function as a closely integrated system.
✓
Answer
- Adrenal medulla originates from embryonic neuro – ectoderm.
- It consists of rounded group of large granular cells called chromaffin cells. They are modified post-ganglionic cells of sympathetic nervous system which have lost normal processes and acquired glandular function.
- These cells are connected with pre-ganglionic fibres of sympathetic nervous system.
- Hence adrenal medulla is an extension of sympathetic nervous system.
- Thus adrenal medulla and sympathetic nervous system functions as a closely integrated system.
