Autonomic Nervous System NCLEX Questions Questions
Question 1 of 5
Movement in which a part of the body moves inferiorly.
Correct Answer: D
Rationale: Depression is the anatomical movement of a body part downward (e.g., shoulder). Action potential is a signal, astrocytes are glia, and interneurons are neurons.
Question 2 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 3 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 4 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.
Question 5 of 5
A person who sees a lion outside will likely have an increase in heart rate. Why?
Correct Answer: B
Rationale: Seeing a lion triggers the sympathetic nervous system, which stimulates cardiac muscle to increase heart rate (fight-or-flight). Parasympathetic slows heart rate.
