#1. Which statement correctly distinguishes neuroglia from neurons?
Correct answer: D. Neuroglia nourish, protect, and insulate neurons, while neurons transmit electrical impulses.
Explanation: Nerve tissue contains neuroglia and neurons. Neuroglia support neurons through nourishment, protection, and insulation, while neurons transmit information as electrical nerve impulses.
Why A is wrong: It assigns the impulse-transmission role to neuroglia.
Why B is wrong: Sensory reception belongs to parts of neurons rather than defining neuroglia.
Why C is wrong: Carrying impulses toward axon terminals is a neuronal function, while nourishment is associated with neuroglia.
#2. When is the parasympathetic nervous system generally more active?
Correct answer: D. During the remaining time and after prolonged sympathetic stimulation
Explanation: The parasympathetic system is more active during the remainder of the time outside sympathetic activation. It also becomes more active after the sympathetic system has been stimulated for too long.
Why A is wrong: Anger stimulates the sympathetic system.
Why B is wrong: Fright stimulates the sympathetic system.
Why C is wrong: Excitement stimulates the sympathetic system.
#3. Which pairing correctly distinguishes the CNS from the PNS?
Correct answer: B. CNS: brain and spinal cord. PNS: nerves throughout the body.
Explanation: The central nervous system consists of the brain and spinal cord. The peripheral nervous system consists of nerves throughout the body.
Why A is wrong: It reverses the two divisions.
Why C is wrong: It mixes structures from the central and peripheral divisions.
Why D is wrong: It also mixes CNS and PNS structures.
#4. Which statement correctly compares electrical and chemical nerve signalling?
Correct answer: B. Electrical signalling occurs within a neuron, while chemical signalling transfers signals between neurons or to a muscle cell.
Explanation: Nerve impulses have electrical and chemical features. Electrical activity carries a signal within a neuron, while chemical processes transfer signals between cells.
Why A is wrong: It reverses the locations of electrical and chemical signalling.
Why C is wrong: Chemical transmission also occurs between a neuron and another cell.
Why D is wrong: Electrical transmission occurs within neurons.
#5. Which statement correctly matches each cerebral hemisphere with body movement?
Correct answer: C. The right controls the left side, and the left controls the right side.
Explanation: The cerebral hemispheres control movement on opposite sides of the body. The right hemisphere relates to the left side, while the left hemisphere relates to the right side.
Why A is wrong: It matches each hemisphere with the same side rather than the opposite side.
Why B is wrong: Control is divided between the two hemispheres.
Why D is wrong: Control is not limited to the right side.
#6. Which statement correctly describes the arachnoid space and cerebrospinal fluid?
Correct answer: C. The space lies between the arachnoid and pia mater, and its fluid circulates around and cushions the brain and spinal cord.
Explanation: The arachnoid space lies between the middle arachnoid layer and inner pia mater. Cerebrospinal fluid fills this space, circulates around the brain and spinal cord, and cushions the CNS against shocks.
Why A is wrong: The stated space lies between the arachnoid and pia mater, and the fluid surrounds both brain and spinal cord.
Why B is wrong: The location is incorrect, and myelin rather than cerebrospinal fluid provides the stated nerve-fibre insulation.
Why D is wrong: Cerebrospinal fluid cushions CNS structures rather than carrying neuronal impulses.
#7. Which pairing correctly describes neurotransmitter storage and release?
Correct answer: B. Axon terminals store neurotransmitters, and the presynaptic membrane releases them.
Explanation: Axon terminals produce and store neurotransmitters. These chemical substances are released from the presynaptic membrane into the synaptic gap.
Why A is wrong: Dendrites receive information rather than serving as the stated neurotransmitter storage site.
Why C is wrong: The myelin sheath does not perform the stated release function.
Why D is wrong: A synapse is a gap rather than the stated storage structure.
#8. Which statement correctly describes the connection between the brain and spinal cord?
Correct answer: D. The brain joins the spinal cord at the lower medulla, and the cord lies within the spinal column.
Explanation: The brain connects with the spinal cord at the lower end of the medulla. The spinal cord lies inside the spinal column, which protects it.
Why A is wrong: The connection occurs at the lower medulla rather than the cerebellum.
Why B is wrong: The connection does not occur at the pons, and the spinal cord lies within the spinal column.
Why C is wrong: The cerebrum is not the stated connection point.
#9. What is the main direction of information carried by an axon?
Correct answer: A. Away from the cell toward the axon terminals
Explanation: The axon carries information away from the neuron cell toward its terminal ends. This direction distinguishes it from dendritic transmission toward the cell body.
Why B is wrong: Dendrites transmit sensory information toward the cell body.
Why C is wrong: The gap between neurons is the synapse.
Why D is wrong: This does not describe the stated direction of axon transmission.
#10. Which three structures are the main parts of a neuron?
Correct answer: B. Dendrite, cell body, and axon
Explanation: A neuron has three main parts: the dendrite, cell body, and axon. Synapses, neurotransmitters, myelin sheaths, and axon terminals relate to nerve signalling but do not form this three-part grouping.
Why A is wrong: A synapse is a gap between neurons.
Why C is wrong: A myelin sheath and axon terminal are not two of the three main neuron parts.
Why D is wrong: A neurotransmitter is a chemical substance rather than one of the three main structures.
#11. Which statement best describes the movement of a nerve impulse?
Correct answer: A. A signal travels along a neuron membrane and then passes from cell to cell.
Explanation: A nerve impulse travels along the neuron membrane beginning where the impulse is applied. Impulses then pass from one cell to another in a chain-like pattern.
Why B is wrong: An impulse also travels along the membrane of a neuron.
Why C is wrong: Nerve signalling extends from one cell to another.
Why D is wrong: This does not describe the stated pattern of nerve-impulse transmission.
#12. Which statement correctly describes the brain’s protection and main parts?
Correct answer: A. The skull protects the brain, whose main parts are the cerebrum, cerebellum, and brain stem.
Explanation: The brain sits within the skull, which protects it. Its three main parts are the cerebrum, cerebellum, and brain stem.
Why B is wrong: The spinal column protects the spinal cord rather than containing the brain.
Why C is wrong: The spinal cord is part of the CNS but not one of the three main brain parts.
Why D is wrong: The spinal cord is not one of the brain’s three main parts.
#13. What is an action potential?
Correct answer: D. A pulse of electricity involving a temporary reversal of cell polarity
Explanation: A nerve impulse travels along the axon as an action potential. It is an electrical pulse involving a temporary reversal of the cell’s polarity.
Why A is wrong: Neurotransmitters are chemical substances stored at axon terminals.
Why B is wrong: A myelin sheath covers and insulates some nerve fibres.
Why C is wrong: A synapse is the gap between neurons.
#14. Which group of effects is associated with injury to the cerebellum?
Correct answer: D. Jerky movement, loss of coordination, and muscle weakness
Explanation: Injury to the cerebellum is associated with jerky movement, reduced coordination, and muscle weakness. These effects match its role in coordinated movement.
Why A is wrong: These are not the stated effects of cerebellar injury.
Why B is wrong: Coughing, swallowing, and vomiting are functions associated with the medulla.
Why C is wrong: These sensory items do not form the stated cerebellar-injury pattern.
#15. Which description best matches the cerebellum?
Correct answer: C. It coordinates body movement and supports smooth voluntary movement and balance.
Explanation: The cerebellum regulates and coordinates body movements. Its control contributes to smooth voluntary muscle movement and balance.
Why A is wrong: Thought and intelligence are associated with the cerebrum.
Why B is wrong: Heart rate and breathing are associated with the medulla.
Why D is wrong: Carrying peripheral impulses is a nerve function rather than the defining role of the cerebellum.
How to Read Your Score
Your score shows how well you understood the material in this attempt. Use 80% or higher as a personal study target for this website quiz, not as an official passing score. A score of 80% or higher shows strong understanding of the material tested. A score from 60% to 79% points to areas that need more review. Below 60%, return to the matching study notes before trying again. Because each attempt uses random questions, your score also depends on the selection you receive. Another attempt might include different questions. Use these ranges only to guide your study decisions.
What Your Mistakes Might Show
Look for patterns in the questions that slowed you down. Missed anatomy or function questions might point to confusion between nervous-system structures and their roles. Comparison or terminology questions might show that related ideas still blend together, such as nervous-system divisions, neuron parts, brain regions, protective structures, nerve functions, or autonomic activity. Missed application or two-step judgment questions might point to trouble using information across more than one idea. Cause-and-effect mistakes might signal that nerve signalling needs another review. Treat these patterns as clues, not proof. Focus first on the area that appears more than once in your mistakes or uncertain answers.
Questions You Guessed On Matter Too
Review more than the questions you got wrong. Mark any question you guessed on, changed several times, found difficult, or answered correctly without feeling sure. A correct guess raises your score, but it does not always show confident understanding. Check why the correct response fits and why the closest wrong answer choice does not fit.
Review and Retake
- Read the explanation for each missed question.
- Identify why the wrong answer choice you picked seemed correct.
- Include questions you guessed on or felt unsure about.
- Review the matching section of the study notes.
- Explain the correct answer in your own words.
- Return later for another attempt after reviewing.
Focus on understanding why each response fits instead of memorizing answers from an earlier attempt. Give yourself more review time before retaking the quiz when the ideas still feel unclear.
Track Your Quiz Progress
The quiz shows your score for the current attempt, but it does not keep a detailed study log. Record the date, your score, one or two areas that caused trouble, and any questions you guessed on or felt unsure about. Use a notebook, planner, spreadsheet, or note on your phone. Another attempt might contain a different selection of questions, so small score changes are normal. Look for stronger understanding and fewer uncertain answers over time instead of chasing one perfect score.
A lower score gives you a useful starting point. Pick one nervous-system area that caused trouble, review it until the differences feel clearer, then return for another attempt and focus on understanding rather than memorizing.
