Question

which is needed for one nerve to communicate with another nerve across a synapse? electrical signals nodes of ranvier neurotransmitters myelinated sheath

Answer 1

Our interconnected neurons help us process different types of information. Synapses are the gaps between neurons. When an impulse reaches the end of one axon, it is now an action potential. This electric signal cannot leap across this gap so as to speak. Special chemicals called neurotransmitters have this role to be possible. The best answer is thus neurotransmitters.
