Test Questions on Autonomic Nervous System Questions
Question 1 of 5
The 4th cranial nerve supplies
Correct Answer: D
Rationale: The trochlear nerve (CN IV) supplies the superior oblique muscle, enabling downward/outward eye movement.
Question 2 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 3 of 5
The human nervous system is capable of a wide range of functions. What is the basic unit of the nervous system?
Correct Answer: C
Rationale: The neuron is the basic functional unit of the nervous system, responsible for transmitting signals. Glial cells support neurons, meninges protect the CNS, and cerebrospinal fluid cushions it, but only neurons conduct electrical impulses.
Question 4 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 5 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.
