Question

Question: Why is the flow of signals in a synapse from axonal end of one neuron to dendritic end of another neuron but not the reverse?​

Answer 1

Answer-

Signals in a synapse flow from axonal end of one neuron to dendritic end of another neuron but not the reverse because when this electrical signal after reaching the axonal end releases a chemical. This chemical then moves towards the dendrite end of the other neuron.

I hope it help u ☺

Answer 2

Question:-

Why is the flow of signals in a synapse from axonal end of one neuron to dendritic end of another neuron but not the reverse?​

• Axon is one in number as compared to the dendrites which are numerous in number.This chemical diffuses towards the dendrite end of next neuron where it generates an electrical signal.
• They receive the signals from the axon and carry them further to other neurons. In this way, it is ensured that nerve impulses travel in only one direction .

Hence, the flow of signals in a synapse happens from axonal end of one neuron to dendritic end of another neuron but not in the reverse direction.
