At the synapse of a motor neuron and striated muscle cell, binding of acetylcholine to nicotinic acetylcholine receptors triggers a rapid increase in permeability of the membrane to both Na+ and K+ ions, leading to depolarization, an action … Witryna21 cze 2024 · Why does an impulse only travel in one direction? Nerve impulse travels in one direction because nerve cells (neurons) connect to each other by synapse. The action potential starts at the axon end (by stimulation from another nerve) and travel along a neurone to the synapse end. Why neurons are unidirectional?
