Web9 de mar. de 2024 · When a nerve impulse reaches the end of an axon, the axon releases chemicals called neurotransmitters. Neurotransmitters travel across the synapse … WebThe incoming nerve impulse from the presynaptic neurons caused the opening of first Na+ channels but needs to reach threshold level to create an action potential. A wave of Na+ channels opens to let ions diffuse into the neuron down the axon. This causes the membrane to depolarize. In response, K+ ions diffuse out of the cell through ion ...
