What is the basic functional unit of the nervous system?
A. Neuron
B. Ganglion
C. Axon
D. Dendrite
Show Answer & Explanation
Correct Answer: A
A neuron is the basic functional unit of the nervous system, responsible for transmitting signals.
Q2
Easy
Which part of the neuron receives signals from other neurons?
A. Axon
B. Dendrites
C. Cell Body
D. Synapse
Show Answer & Explanation
Correct Answer: B
Dendrites are the extensions of a neuron that receive signals from other neurons.
Q3
Easy
Which type of neuron carries messages from the brain to muscles?
A. Sensory Neuron
B. Motor Neuron
C. Interneuron
D. Glial Cell
Show Answer & Explanation
Correct Answer: B
Motor neurons transmit impulses from the brain and spinal cord to muscles, enabling movement.
Q4
Medium
What is the fundamental structural and functional unit of the nervous system?
A. Neuron
B. Glial cell
C. Axon
D. Dendrite
Show Answer & Explanation
Correct Answer: A
Neurons are the basic building blocks of the nervous system, responsible for transmitting signals.
Q5
Medium
Which part of the neuron is primarily responsible for receiving signals?
A. Axon
B. Dendrite
C. Myelin sheath
D. Synapse
Show Answer & Explanation
Correct Answer: B
Dendrites receive incoming signals from other neurons.
Q6
Medium
What type of neuron carries impulses away from the central nervous system?
A. Sensory neuron
B. Motor neuron
C. Interneuron
D. Reflex neuron
Show Answer & Explanation
Correct Answer: B
Motor neurons transmit impulses from the CNS to muscles or glands.
Q7
Medium
What is the speed of nerve impulse transmission in myelinated fibers?
A. 5-10 m/s
B. 20-120 m/s
C. 50-100 m/s
D. 1-5 m/s
Show Answer & Explanation
Correct Answer: B
Myelinated fibers transmit impulses at speeds of 20-120 m/s due to saltatory conduction.
Q8
Hard
Which part of the neuron is primarily responsible for receiving signals from other neurons?
A. Axon
B. Dendrite
C. Myelin sheath
D. Soma
Show Answer & Explanation
Correct Answer: B
Dendrites are specialized extensions of neurons that receive signals from other neurons or sensory receptors.
Q9
Hard
What is the primary function of the myelin sheath in neurons?
A. To transmit signals
B. To insulate the axon
C. To produce neurotransmitters
D. To connect neurons
Show Answer & Explanation
Correct Answer: B
The myelin sheath insulates the axon, speeding up the transmission of electrical impulses along the nerve cell.
Q10
Hard
Which part of the brain is responsible for coordinating voluntary movements?
A. Medulla oblongata
B. Cerebellum
C. Thalamus
D. Cerebrum
Show Answer & Explanation
Correct Answer: B
The cerebellum is responsible for coordination and regulation of muscular activity and balance.
