Test Questions on Autonomic Nervous System Questions
Question 1 of 5
The transmitter substance in the presynaptic neuron is contained in the:
Correct Answer: B
Rationale: Neurotransmitters (e.g., acetylcholine) are stored in synaptic vesicles (neuron vesicles) in the presynaptic terminal, released into the cleft upon signal.
Question 2 of 5
Which of the following is in the peripheral nervous system?
Correct Answer: D
Rationale: Satellite cells are PNS glial cells supporting neuron cell bodies in ganglia. The others are CNS-specific (oligodendrocytes myelinate, ependymal line ventricles, microglia are immune).
Question 3 of 5
A client who recently experienced a stroke is displaying deficits in speech. Recalling concepts of physiology, which lobes of the brain would the nurse consider to be likely affected by the stroke?
Correct Answer: D
Rationale: Speech deficits (e.g., Broca’s area in frontal lobe, Wernicke’s in temporal lobe) suggest frontal and temporal lobe involvement. Parietal handles sensation, occipital vision.
Question 4 of 5
While teaching the client about a diagnosed endocrine disorder, which area of the brain would the nurse include as the center in the brain that regulates hormone production?
Correct Answer: B
Rationale: The diencephalon (hypothalamus, pituitary) regulates hormone production. Cerebrum handles cognition, brainstem vital functions, cerebellum coordination.
Question 5 of 5
Neuropeptides are:
Correct Answer: A
Rationale: Neuropeptides are small protein-like molecules that act as neurotransmitters or neuromodulators, released by neurons to communicate with other cells. They are not glial cells, not produced by the choroid plexus (which makes CSF), nor nutrients.
