Introduction

Neurotransmitter used in somatic motor neurons

Acetylcholine (cholinergic neurotransmission)

What type of acetylcholine receptor is expressed on the skeletal muscle

Nicotinic receptor

Neurotransmitter used in the autonomic nervous system

Acetylcholine (cholinergic neurotransmission)

Noradrenaline (noradrenergic neurotransmission)

ANS neurons convey information from where to where controlling what

ANS neurons convey information from the CNS to the internal organs, glands, smooth muscles and vascular muscles to regulate autonomous/automatic bodily functions

In the parasympathetic nervous system, the preganglionic & the postganglionic neuron are cholinergic/noradrenergic

Both cholinergic

In the parasympathetic nervous system, the ganglia communicate via cholinergic transmission at what receptors

Nicotinic

In the parasympathetic nervous system, communication (cholinergic transmission) at the target tissues is via what receptors

Muscarinic

In the sympathetic nervous system, the preganglionic & the postganglionic neuron are cholinergic/noradrenergic

Preganglionic neuron = cholinergic

Postganglionic neuron = noradrenergic

In the sympathetic nervous system, the ganglia communicate via what receptors

nicotinic receptors

In the sympathetic nervous system, communication at the target tissues is via what receptors

Adrenoceptors

How does the level of organisation differ between the ANS & somatic motor systems

Effect of parasympathetic stimulation on vascular smooth muscle

No effect - only sympathetic stimulation has an effect on vascular smooth muscle 

Effect of sympathetic stimulation on vascular smooth muscle

Contraction to increase bp

Effect of sympathetic stimulation on glands

Glandular secretions decrease

Effect of sympathetic stimulation on iris & pupils

Iris relaxes

Pupils dilate

Effect of sympathetic stimulation on tears

Decrease (glands decrease)

Effect of sympathetic stimulation on bronchi

Bronchi widen

Effect of sympathetic stimulation on bladder

Relaxation - reduced emptying
