Autonomic Nervous System NCLEX Questions Questions
Question 1 of 5
Clusters of neuron cell bodies found in the CNS are termed:
Correct Answer: D
Rationale: In the CNS, clusters of neuron cell bodies are called nuclei. Ganglia are PNS equivalents.
Question 2 of 5
An elderly client has suffered a brainstem hemorrhage. The nurse is aware that the brainstem controls which of the following functions?
Correct Answer: C
Rationale: The brainstem (e.g., medulla) regulates vital functions like blood pressure. Endocrine function is hypothalamic, sleep involves multiple areas, language is cortical.
Question 3 of 5
The third ventricle is located in the:
Correct Answer: B
Rationale: The third ventricle is a midline cavity within the diencephalon, part of the forebrain (prosencephalon). It is not in the cerebrum alone (telencephalon), hindbrain (rhombencephalon), midbrain (mesencephalon), or cerebellum.
Question 4 of 5
Clusters of neuron cell bodies embedded in the white matter of the brain are referred to as:
Correct Answer: A
Rationale: In the CNS, clusters of neuron cell bodies are called nuclei (e.g., basal nuclei). Gyri are cortical ridges, ganglia are PNS neuron clusters, and fasciculi are axon bundles.
Question 5 of 5
Which of the following is not involved with motor impulses or motor coordination?
Correct Answer: D
Rationale: All listed structures are involved in motor functions: red nucleus (midbrain motor relay), cerebellum (coordination), basal ganglia (movement refinement), precentral gyrus (primary motor cortex). 'None of the above' is incorrect.
