Vedclass · Answer

(A) The correct answer is $A$. In a neuron,the nerve impulse travels from the dendritic end towards the axonal end. At the axonal end (synaptic knob),the electrical impulse triggers the release of neurotransmitters (chemicals) into the synapse. These chemicals diffuse across the synapse and bind to receptors on the dendrite of the next neuron,where they generate a new electrical impulse. Option $A$ is incorrect because it states that the electrical impulse at the dendritic end releases chemicals to generate an impulse at the axonal end of another neuron,which reverses the actual direction of signal transmission.
