Which of the following feature is not related to neuron?
Correct answer: B. Regeneration
- A. Conduction
- B. Regeneration
- C. Reflex
- D. Movement
Explanation
Regeneration is not a normal defining function of neurons, which are specialized mainly for receiving, conducting and transmitting impulses; most mature central neurons have very limited regenerative ability. Students may choose movement because motor neurons do not themselves contract muscles, but they control movement by transmitting impulses to muscles.

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.
