Test Questions on Autonomic Nervous System Questions
Question 1 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 2 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 3 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 4 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.
Question 5 of 5
A regeneration tube in the PNS helps direct further growth of after an injury.
Correct Answer: B
Rationale: In the PNS, Schwann cells form a regeneration tube to guide axon regrowth after injury. Dendrites receive signals, soma is the cell body, and myelin sheath insulates.
