Question

Compare and contrast the sympathetic nervous system and the parasympathetic nervous system in terms of neurotransmitters secreted by pre and post ganglionic neurons as well as receptors found on post ganglionic neurons and effector cells.

Answer 1

	Sympathetic	parasympathetic
Outflow	thoraco lumbar outflow	cranio sacral outflow
Pre Ganglionic neurotransmitter	Acetylcholine	Acetylcholine
Post Ganglionic neurotransmitter	Nor-epinephrine	Acetylcholine
Receptors on post G neuron	Nicotinic receptors (N​​​​​​G)	Nicotinic receptors (N​​​​​​G)
Receptors on effectors	alpha and Beta adrenergic receptors	Muscarinic receptors

Exception to above -

Sympathetic supply to sweat gland - Muscarinic receptors on effectors.
