Key concepts: Neural Control and Coordination (Class 11 Biology)
Neurons convey information as fast electrical and chemical signals. This chapter covers neuron structure, the ionic basis of the resting and action potentials, impulse conduction, synaptic transmission, the organisation of central and peripheral nervous systems, the reflex arc, and the divisions of the human brain.
- Neuron
- The neuron is the structural and functional unit: dendrites receive signals, the cell body integrates them, and one axon conducts the impulse onward.
- Types of neurons
- By structure neurons are multipolar (brain), bipolar (retina) or unipolar; myelinated axons conduct impulses faster than unmyelinated ones.
- Resting potential
- At rest the membrane is polarised (~−70 mV): K⁺ high inside, Na⁺ high outside, kept by the Na⁺–K⁺ pump and selective permeability.
- Action potential
- A threshold stimulus opens Na⁺ channels; Na⁺ floods in and the membrane depolarises, reversing to about +30 mV at that point.
Neural Control and Coordination — important questions & MCQs with answers (Class 11 Biology)
14 solved questions from this chapter's difficulty levels, each with its answer and explanation. The other 76 are timed and scored when you sign in.
- Q1Easy
Long process of a neuron carrying impulse away from cell body:
A.DendriteB.Axon✓ CorrectC.SynapseD.SomaAnswer: B. Axon
Explanation: The axon is the long process that conducts impulses away from the cell body toward the synaptic knob; dendrites are the short, branched processes that carry impulses toward the cell body, the reverse direction.
- Q2Easy
Largest part of human brain:
A.MedullaB.CerebellumC.Cerebrum✓ CorrectD.PonsAnswer: C. Cerebrum
Explanation: The cerebrum, forming the bulk of the forebrain with its two hemispheres, is the largest and most developed part of the human brain; the cerebellum is the second largest but only a fraction of its volume.
- Q3Easy
Human nervous system is broadly divided into:
A.Sympathetic and parasympatheticB.CNS and PNS✓ CorrectC.Sensory and motorD.Somatic and visceralAnswer: B. CNS and PNS
Explanation: The nervous system's primary anatomical split is CNS (brain and spinal cord) versus PNS (all nerves outside it); sympathetic/parasympathetic is a functional division one level down, inside the autonomic part of PNS.
- Q4Easy
The longest process of a neuron is:
A.Axon✓ CorrectB.DendriteC.SomaD.TelodendronAnswer: A. Axon
Explanation: The axon, often over a metre long in humans, is the neuron's longest process and carries impulses away from the soma to the synapse; dendrites are shorter, branched processes that receive incoming signals instead.
- Q5Easy
Largest part of human brain is:
A.CerebellumB.Cerebrum✓ CorrectC.MedullaD.ThalamusAnswer: B. Cerebrum
Explanation: Cerebrum, the two large hemispheres of the forebrain, is the largest region of the human brain and handles higher cognitive functions; the cerebellum is much smaller and governs balance and motor coordination instead.
- Q6Easy
Autonomic nervous system has two divisions:
A.Sensory and motorB.Somatic and visceralC.Sympathetic and parasympathetic✓ CorrectD.CNS and PNSAnswer: C. Sympathetic and parasympathetic
Explanation: The autonomic nervous system, controlling involuntary organ functions, splits into the sympathetic (fight-or-flight, noradrenaline) and parasympathetic (rest-and-digest, acetylcholine) divisions — somatic/visceral is a different classification.
- Q7Medium
Resting membrane potential of neuron is approximately:
A.−70 mV✓ CorrectB.+30 mVC.0 mVD.−100 VAnswer: A. −70 mV
Explanation: Resting potential is about −70 mV, inside negative relative to outside, maintained by the Na⁺/K⁺-ATPase pumping 3 Na⁺ out for every 2 K⁺ in; +30 mV is instead the peak of the action potential, not the resting state.
- Q8Medium
Cerebellum is responsible for:
A.Memory onlyB.VisionC.Balance and coordination of movements✓ CorrectD.Heart rateAnswer: C. Balance and coordination of movements
Explanation: Cerebellum coordinates fine motor movements, posture and balance by comparing intended and actual movement; it does not store memory (cerebrum) or process vision (occipital lobe) or set heart rate (medulla).
- Q9Medium
Sympathetic stimulation typically causes:
A.Bladder emptyingB.Pupil constriction and lower HRC.Increased salivationD.Pupil dilation and heart rate increase✓ CorrectAnswer: D. Pupil dilation and heart rate increase
Explanation: Sympathetic activation is the 'fight-or-flight' response: it dilates pupils (mydriasis) and raises heart rate via noradrenaline; pupil constriction, a slowed heart rate and increased salivation are parasympathetic effects instead.
- Q10Medium
Saltatory conduction of impulse occurs in:
A.Dendrites onlyB.Unmyelinated fibresC.Smooth muscleD.Myelinated nerve fibres✓ CorrectAnswer: D. Myelinated nerve fibres
Explanation: Saltatory conduction lets the nerve impulse jump between successive nodes of Ranvier along a myelinated fibre, greatly speeding transmission; unmyelinated fibres lack these gaps and propagate the impulse continuously, more slowly.
- Q11Medium
Visual area of cerebrum is located in:
A.Frontal lobeB.Occipital lobe✓ CorrectC.Temporal lobeD.Parietal lobeAnswer: B. Occipital lobe
Explanation: The primary visual cortex sits in the occipital lobe at the back of the cerebrum; the temporal lobe instead handles hearing and the frontal lobe governs motor control and reasoning, not vision.
- Q12Hard
Across a chemical synapse, signal is transmitted by:
A.Neurotransmitters✓ CorrectB.Direct currentC.Magnetic fieldsD.LightAnswer: A. Neurotransmitters
Explanation: At a chemical synapse, Ca²⁺ influx into the presynaptic terminal triggers neurotransmitter release (e.g. acetylcholine), which diffuses across the cleft and binds postsynaptic receptors; only electrical synapses pass current directly via gap junctions.
- Q13Hard
Medulla oblongata controls:
A.Speech onlyB.VisionC.Heart rate, breathing, blood pressure✓ CorrectD.HearingAnswer: C. Heart rate, breathing, blood pressure
Explanation: Medulla oblongata houses the vital autonomic centres for heart rate, respiratory rhythm and blood pressure, plus reflexes like vomiting and swallowing; speech production is instead a cortical (Broca's area) function.
- Q14Hard
Assertion: Sympathetic and parasympathetic systems act antagonistically. Reason: They use the same postganglionic transmitter throughout.
A.Both true; R explains AB.A true, R false✓ CorrectC.Both falseD.A false, R trueAnswer: B. A true, R false
Explanation: Sympathetic and parasympathetic systems genuinely act antagonistically, but the given reason is false: sympathetic postganglionic neurons release noradrenaline while parasympathetic ones release acetylcholine, not one shared transmitter.
