Question

Does a nerve impulse travel from the branches of axon to axon to cell body, or from the cell body to axon to the branches of the axon?

Answer 1

Nerves impulse first arrive at dendrites (branches of cell body). After that it moves to cell body and then it travels down the axon to an axon terminal . This axon terminal lie near to the dendrites of neighbouring neurons.

Explanation:

We can also summarize it as:
Dendrites `to` Cell body `to` Axon `to` Axon terminal
