Question
The flow of impulse in a nerve is unidirectional. Give reason.
✓
Answer
The neurotransmitters involved in the conduction of nerve impulse across the synapse, are present only in the axon terminals and not in the dendrites or cell body.
In a synapse, the impulse travels from the axon terminal to the dendrite or cell body of the next neuron; hence, the flow of nerve impulse is unidirectional.
