Autonomic Nervous System NCLEX Questions Questions
Question 1 of 5
A malignant tumor that consists of immature nerve cells (neuroblasts); occurs most commonly in the abdomen and most frequently in the suprarenal glands.
Correct Answer: B
Rationale: Neuroblastoma is a malignant tumor of immature neuroblasts, common in children’s adrenal glands. Axoplasm is axon cytoplasm, action potential is a signal, and axosomatic is a synapse.
Question 2 of 5
Expanded distal end of an axon terminal that contains synaptic vesicles.
Correct Answer: A
Rationale: Synaptic end bulbs are the expanded ends of axon terminals containing synaptic vesicles. Axon terminals are broader, vesicles are contents, and neurotransmitter is a chemical.
Question 3 of 5
The nerve cell that is activated by the release of a neurotransmitter from another neuron and carries nerve impulses away from the synapse.
Correct Answer: B
Rationale: The postsynaptic neuron receives neurotransmitters and propagates impulses away from the synapse. ANS is a system, axon is a neuron part, and depression is a movement.
Question 4 of 5
If a postsynaptic cell receives EPSPs but not enough to reach the threshold, which of the following will happen?
Correct Answer: B
Rationale: If excitatory postsynaptic potentials (EPSPs) don’t reach the threshold (~-55 mV), no action potential is triggered due to the all-or-none principle. Action potentials don’t vary in strength or number here.
Question 5 of 5
Which neuronal feature is described according to function?
Correct Answer: B
Rationale: The cell body (soma) houses the nucleus and organelles, supporting neuron function. Dendrites receive signals, and axons send them.
