NCLEX Neurology Practice Questions Questions
Question 1 of 5
The effect of a sending neuron on a receiving neuron is typically greater when neurotransmitters bind to the receiving neuron and the synapse is the base of the receiving cell's axon.
Correct Answer: A
Rationale: Synapses closer to the axon hillock (base of the axon) have a greater impact due to less signal attenuation, and more neurotransmitter enhances the effect.
Question 2 of 5
Our biological clock, which regulates the sleep-wake cycle, is housed within the
Correct Answer: B
Rationale: The suprachiasmatic nucleus in the hypothalamus controls the circadian rhythm, including sleep-wake cycles.
Question 3 of 5
Like other systems in the body, the nervous system is composed of organs, principally the brain, spinal cord, nerves, and
Correct Answer: A
Rationale: The nervous system includes organs like the brain, spinal cord, nerves, and ganglia (clusters of neuron cell bodies in the PNS), whereas axons and neurons are components, and dura mater is a protective layer.
Question 4 of 5
The neuron processes that normally receives incoming stimuli are called:
Correct Answer: B
Rationale: Dendrites are the branched processes of neurons that receive incoming signals and convey them toward the cell body.
Question 5 of 5
The elevated ridges of tissue on the surface of the cerebral hemispheres are known as while the shallow grooves are termed
Correct Answer: B
Rationale: Gyri are the ridges and sulci are the grooves on the cerebral cortex, increasing surface area for neural processing.
