Neurotransmitters in ANS and receptors

[Autonomic nervous system : Parasympathetic and Sympathetic Nervous system]

parasympathetic : Ach -> Ach

Sympathetic : Ach -> Norepi / Ach to adrenal medulla -> Norepi, epi

 

 

 

 

 

(Sympathetic Nervous system)

[ Adrenaline,Noradrenaline & a,b receptors ]

 

 => Both adrenaline and noradrenaline work on alpha and beta receptors

However, adrenaline has a greater effect on beta receptors compared to noradrenaline

So to make it simple, 

Adrenaline -> beta receptors : heart, lungs, and arteries/ skeletal muscles

Noradrenaline -> alpha receptors : arteries

 

 

 

(Parasympathetic nervous system)

[Acethylcholine & Nicotinic receptors, muscarinic receptors ]
