Question

Q24 How is impulse conducted along a non-myelinated nerve fibre.​

Answer 1

Answer:

Here is your answer

Explanation:

At rest, Na+ channels are closed. When impulse arrives at the neuron, it causes them to open. There is more of Na+ outside, so they enter the axon through their channels due to simple diffusion. Moreover, the ions are positively charged so they are attracted to the negative inside of axon.
