Q1
Easy
What part of the neuron is primarily responsible for receiving signals from other neurons?
A.
Axon
B.
Dendrites
C.
Soma
D.
Myelin Sheath
Show Answer & Explanation
Correct Answer: B
Dendrites are the branching extensions of a neuron that receive signals from other neurons, making them crucial for signal reception.
Q2
Easy
Which part of the neuron is responsible for transmitting impulses away from the cell body?
A.
Dendrites
B.
Axon
C.
Neurotransmitters
D.
Soma
Show Answer & Explanation
Correct Answer: B
The axon is the long, slender projection of a neuron that conducts electrical impulses away from the neuron's cell body.
Q3
Easy
What is the role of the myelin sheath in a neuron?
A.
To increase the speed of impulse conduction
B.
To store neurotransmitters
C.
To maintain cell shape
D.
To receive signals
Show Answer & Explanation
Correct Answer: A
The myelin sheath acts as an insulating layer that increases the speed of electrical impulse conduction along the axon.
Q4
Medium
Which part of the neuron is primarily responsible for receiving incoming signals?
A.
Axon
B.
Soma
C.
Dendrites
D.
Myelin sheath
Show Answer & Explanation
Correct Answer: C
Dendrites are specialized extensions of the neuron that receive signals from other neurons, making them crucial for signal reception.
Q5
Medium
What is the function of the myelin sheath in a neuron?
A.
To transmit impulses
B.
To increase the speed of impulse transmission
C.
To store neurotransmitters
D.
To produce energy
Show Answer & Explanation
Correct Answer: B
The myelin sheath acts as an insulating layer around the axon, which increases the speed of electrical impulses through saltatory conduction.
Q6
Medium
In which part of the neuron does action potential primarily occur?
A.
Soma
B.
Dendrites
C.
Axon Hillock
D.
Myelin sheath
Show Answer & Explanation
Correct Answer: C
The axon hillock is the site where action potentials are generated due to the summation of excitatory and inhibitory signals.
Q7
Medium
Which type of neuron conducts impulses away from the central nervous system?
A.
Motor neurons
B.
Sensory neurons
C.
Interneurons
D.
Glial cells
Show Answer & Explanation
Correct Answer: A
Motor neurons transmit impulses from the central nervous system to muscles or glands, thereby facilitating movement or action.
Q8
Hard
Which part of the neuron is primarily responsible for receiving signals from other neurons?
A.
Axon
B.
Dendrite
C.
Cell Body
D.
Myelin Sheath
Show Answer & Explanation
Correct Answer: B
Dendrites are specialized extensions of neurons that receive signals from other neurons, making them crucial for neural communication.
Q9
Hard
What is the primary function of the myelin sheath in neurons?
A.
To support the neuron structurally
B.
To facilitate the transmission of action potentials
C.
To store neurotransmitters
D.
To produce energy for cellular metabolism
Show Answer & Explanation
Correct Answer: B
The myelin sheath insulates the axon and enhances the speed of electrical impulses via saltatory conduction, thereby facilitating action potential transmission.
Q10
Hard
In which part of the neuron do action potentials typically begin?
A.
Dendrite
B.
Soma
C.
Axon Hillock
D.
Synapse
Show Answer & Explanation
Correct Answer: C
Action potentials typically initiate at the axon hillock, where the sum of excitatory and inhibitory signals determines if an action potential will occur.
