Test Questions on Autonomic Nervous System Questions
Question 1 of 5
Which pairing of nerve and organ innervated is incorrect?
Correct Answer: D
Rationale: Abducens (VI) innervates the lateral rectus eye muscle, not facial muscles (facial nerve, VII). Other pairings are correct.
Question 2 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 3 of 5
The tightly packed coil of the Schwann cell plasma membrane that encircles certain kinds of axons is called:
Correct Answer: A
Rationale: The myelin sheath is formed by Schwann cells (PNS) wrapping around axons. Neurilemma is the outer Schwann cell layer, nodes are gaps, gray matter is unmyelinated.
Question 4 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 5 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.
