Test Questions on Autonomic Nervous System Questions
Question 1 of 5
The fifth cranial nerve supplies
Correct Answer: A
Rationale: The trigeminal nerve (CN V) supplies the temporalis (V3 motor). The external nasal is V1, earlobe is C2-C3, and occiput is C2.
Question 2 of 5
Certain metabolic diseases can affect the nervous system. For instance, people with diabetes can develop a nervous system problem called diabetic neuropathy. What are the symptoms of diabetic neuropathy?
Correct Answer: D
Rationale: Diabetic neuropathy (peripheral nerve damage from diabetes) can cause constipation/diarrhea (autonomic), rapid heartbeat (autonomic), and pain in feet (sensory). 'All of the above' encompasses these common symptoms.
Question 3 of 5
Flat neuroglial cell that surrounds cell bodies of peripheral nervous system ganglia to provide structural support and regulate the exchange of material between a neuronal cell body and interstitial fluid.
Correct Answer: B
Rationale: Satellite cells are flat neuroglia that encase PNS ganglion cell bodies, providing support and regulating nutrient exchange. Dendrites are neuron parts, depression is unrelated, and tracts are CNS axon bundles.
Question 4 of 5
Propagation of an action potential (nerve impulse) in a step-by-step depolarization of each adjacent area of an axon membrane.
Correct Answer: A
Rationale: Continuous conduction is the step-by-step depolarization along unmyelinated axons. Epinephrine is a hormone, myelin sheath insulates, and receptors bind neurotransmitters.
Question 5 of 5
The portion of the brain and spinal cord containing neuronal cell bodies, dendrites, and unmyelinated axons.
Correct Answer: A
Rationale: Gray matter consists of neuronal cell bodies, dendrites, and unmyelinated axons in the CNS. White matter is myelinated axons, cerebral cortex is a gray matter region, and synaptic vesicles store neurotransmitters.
