Test Questions on Autonomic Nervous System Questions
Question 1 of 5
The infratrochlear nerve supplies the
Correct Answer: C
Rationale: The infratrochlear nerve (V1) supplies sensation to the bridge of the nose and medial eyelid.
Question 2 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 3 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 4 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 5 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.
