Neurological Assessment Questions Questions
Question 1 of 5
Which type of axon conducts nerve impulses at the fastest speed?
Correct Answer: D
Rationale: Large-diameter, myelinated axons conduct fastest due to low resistance and saltatory conduction. [Level: Comprehension]
Question 2 of 5
Saltatory conduction occurs in myelinated axons and involves:
Correct Answer: B
Rationale: Saltatory conduction jumps between nodes, speeding transmission in myelinated axons. [Level: Comprehension]
Question 3 of 5
The synapse between a motor neuron and a skeletal muscle cell is an example of a:
Correct Answer: C
Rationale: The neuromuscular junction is a specialized chemical synapse for muscle activation. [Level: Knowledge]
Question 4 of 5
Oligodendrocytes are responsible for:
Correct Answer: C
Rationale: Oligodendrocytes myelinate CNS axons, enhancing conduction speed. [Level: Knowledge]
Question 5 of 5
Which meningeal layer is closely associated with blood vessels and follows the contours of the brain's surface?
Correct Answer: A
Rationale: The pia mater adheres to the CNS surface, following its contours and blood vessels. [Level: Knowledge]
