ABSTRACT
To answer a question on this subject well, you need to know the structure and function of the autonomic nervous system (ANS). This is covered in a separate chapter (see Study Guide 1, Chapter 35). This question could easily go on to explore other drugs that modulate the ANS, such as:
Nicotinic AChR antagonists acting at ganglia, e.g. trimetaphan
mAChR agonists, e.g. pilocarpine
Adrenoceptor antagonists, e.g. α and β-blockers
Adrenoceptor agonists, e.g. adrenaline.
