Which of the following statement about neuron is incorrect___________________?
Correct answer: D. Like all the living cell, when they mature and divide to form similar cells
- A. They not only conduct impulses but also generate them
- B. They are not the only cellular component of nervous system
- C. They may show limited regenerative capabilities
- D. Like all the living cell, when they mature and divide to form similar cells
Explanation
Mature neurons are highly specialized and usually remain in the non-dividing G0 phase, although limited repair or regeneration can occur in some situations. They conduct impulses and glial cells provide additional cellular support in nervous tissue. The likely alternative is a, but neurons can generate action potentials as well as conduct them, whereas the claim that mature neurons divide to form similar cells is incorrect.

About Neurons and Nerve Impulse
Neurons receive and transmit information through dendrites, the cell body and axons. The topic explains resting potential, depolarization, repolarization, refractory periods and saltatory conduction, followed by synaptic transmission through neurotransmitters. An action potential is distinct from the graded potential produced at a receptor.
