Questions and Answers

Match the following terms with their correct descriptions:

Somatic motor nervous system = One neuron system Autonomic Nervous System = Two neuron system Preganglionic neuron = Myelinated neuron before the ganglia Postganglionic neuron = Unmyelinated neuron after the ganglia

Match the following neurotransmitters with their roles in the autonomic nervous system:

Acetylcholine = Released by the first neuron; always excitatory Epinephrine or norepinephrine = Released in the sympathetic nervous system Second neuron's neurotransmitter = Determines whether sympathetic or parasympathetic response

Match the following with their correct divisions in the autonomic nervous system:

Sympathetic division = Fight or flight; excitatory Parasympathetic division = Rest and digest; inhibitory

Match the following terms with their locations in the autonomic nervous system:

Ganglia of the sympathetic trunk = Located inside the trunk Prevertebral ganglia = Located outside the trunk Signup and view all the answers

Match the neurotransmitter with the correct type of neuron:

Acetylcholine = Postganglionic neuron Norepinephrine = Sympathetic postganglionic neuron Epinephrine = Adrenergic neuron Signup and view all the answers

Match the location with the type of ganglia:

On or near the effectors = Terminal ganglia In the sympathetic chain = Prevertebral ganglia Located on or near the carotid arteries = Cephalic periarterial nerves In or near visceral organs = Visceral ganglia Signup and view all the answers

Match the type of receptors with the neurotransmitter:

Nicotinic receptors = Acetylcholine Adrenergic receptors = Norepinephrine Cholinergic receptors = Epinephrine Excitatory receptors = Acetylcholine Signup and view all the answers

Match the division with the nerves it originates from:

Parasympathetic Division = CN III, VII, IX, X and SN S2-S4 Sympathetic Division = Sympathetic chain and splanchnic nerves Sweat glands exception = Releases acetylcholine Adrenal medulla pathway = Leaves trunk without synapsing Signup and view all the answers

Match the pathway with its description:

Preganglionic neuron synapses at same level = Synapse right here Neuron leaves trunk without synapsing to prevertebral ganglia = Splanchnic nerve Neuron leaves trunk without synapsing to adrenal medulla = Chromaffin cells synapse Postganglionic fibers going to visceral organs directly from sympathetic chain = Sympathetic nerves pathway Signup and view all the answers

Match the effect on adrenergic receptors with its description:

Excitatory or inhibitory effect on effector tissue = Effect of norepinephrine Always excitatory effect on neurons = Nicotinic receptors activation Excitatory effect on all postganglionic neurons except sweat glands = Acetylcholine release by postganglionic neurons Mainly inhibitory effect in most cases = Effect of cholinergic neurons Signup and view all the answers
