Test Questions on Autonomic Nervous System Questions
Question 1 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 2 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 3 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.
Question 4 of 5
An electrical signal that propagates along the membrane of a muscle fiber.
Correct Answer: D
Rationale: A muscle action potential is the electrical signal in muscle fibers, triggering contraction. Interneurons connect neurons, Wallerian degeneration is axon breakdown, and stimulus is an activator.
Question 5 of 5
Hormone secreted by the adrenal medulla that produces actions similar to those that result from sympathetic stimulation.
Correct Answer: A
Rationale: Epinephrine, secreted by the adrenal medulla, enhances sympathetic responses (e.g., fight-or-flight). Norepinephrine is similar but listed separately, ACh and dopamine are neurotransmitters.
