Test Questions on Autonomic Nervous System Questions
Question 1 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 2 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.
Question 3 of 5
The study of the normal functioning and disorders of the nervous system.
Correct Answer: C
Rationale: Neurology is the study of nervous system function and disorders. Nerve is a structure, oligodendrocytes are glia, and parasympathetic is a system.
Question 4 of 5
Aggregations or bundles of myelinated and unmyelinated axons located in the brain and spinal cord.
Correct Answer: D
Rationale: White matter is bundles of myelinated and unmyelinated axons in the CNS. Wallerian degeneration is axon breakdown, SNS is a system, and spinal nerves are PNS.
Question 5 of 5
A fatal disease caused by a virus that reaches the CNS via fast axonal transport.
Correct Answer: B
Rationale: Rabies is a viral disease transmitted via bites, reaching the CNS through axonal transport, causing neurological symptoms and death. Effectors are targets, myelin sheath is insulation, and axosomatic is a synapse.
