What is the function of synapse________________?
Correct answer: B. To decrease the speed of nerve impulse
- A. To allow nerve impulse to move in backward direction
- B. To decrease the speed of nerve impulse
- C. To stop the nerve impulse
- D. To provide cytoplasmic connection between neurons.
Explanation
A synapse produces a small synaptic delay because neurotransmitter release and reception take time, so transmission across a synaptic pathway is slower. Option d is a common mistake because a synaptic cleft is a gap, not a direct cytoplasmic connection between neurons.

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.
