Pharmacology of the ANS

Question 1

Describe the transmitters of the sympathetic ANS (and their receptors)

Answer 1

The sympathetic nervous system is regulated by noradrenaline and adrenaline receptors, there can be a1/2 or b1/2.
These act on adrenergic receptors.

Question 2

Describe the transmitters of the parasympathetic ANS (and their receptors).

Answer 2

The parasympathetic nervous system is regulated by acetyl choline.
Could be muscarinic or nicotinic.
They act in cholinergic receptors.

Question 3

Describe parasympathetic postganglionic transmission.

Answer 3

Involves muscarinic receptor agonists.
These mimic the effect of the parasympathetic nervous system (i.e. slow heart rate
