Autonomic Nervous System NCLEX Questions Questions 
            
        Question 1 of 5
Any stress that changes a controlled condition; any change in the internal or external environment that excites a sensory receptor, a neuron, or a muscle fiber.
Correct Answer: D
Rationale: A stimulus is any change (e.g., light, pressure) that activates sensory receptors, neurons, or muscles. Enteric plexuses are digestive nerves, axoplasm is axon cytoplasm, and synaptic cleft is a synapse gap.
Question 2 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 3 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 4 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 5 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.
