Questions About Nervous System Questions
Question 1 of 5
Any disorder that affects the nervous system but particularly a disorder of a cranial or spinal nerve. An example is facial neuropathy (Bell's palsy), a disorder of the facial (VII) nerve.
Correct Answer: D
Rationale: Neuropathy is a disorder affecting nerves, such as Bell’s palsy (facial nerve). Synaptic cleft is a synapse gap, parasympathetic is a system, and ACh is a neurotransmitter.
Question 2 of 5
The part of the nervous system that lies outside the central nervous system, consisting of nerves and ganglia.
Correct Answer: D
Rationale: The peripheral nervous system (PNS) includes nerves and ganglia outside the CNS. Neuroblastoma is a tumor, ANS is a PNS subdivision, and action potentials are signals.
Question 3 of 5
Neuroglial cell that covers choroid plexuses and produces cerebrospinal fluid (CSF); it also lines the ventricles of the brain and probably assists in the circulation of CSF.
Correct Answer: C
Rationale: Ependymal cells line ventricles, produce CSF, and aid its circulation. Neurology is a field, nerve fiber is an axon, and neurotransmitter is a chemical.
Question 4 of 5
Synapse from axon to cell body.
Correct Answer: C
Rationale: An axosomatic synapse occurs from an axon to a neuron’s cell body. Oligodendrocytes are glia, agonist is a drug term, and SNS is a system.
Question 5 of 5
Muscle fiber (cell) in the ventricular tissue.
Correct Answer: A
Rationale: Purkinje cells are specialized muscle fibers in the heart’s ventricles, conducting electrical signals for contraction. GBS is a disorder, dendrites and axon terminals are neuron parts.
