Unlabeled action potential
WebNerve impulses are action potentials propagated along the axons of neurons. Propagation of nerve impulses is the result of local currents that cause each successive part of the axon to reach the threshold potential. Synapses are junctions between neurons and between neurons and receptor or effector cells. Web1. Action potential arrives at axon terminal of motor neuron. 2. Voltage-gated calcium channels open. Calcium enters the axon terminal, moving down its electrochemical gradient. 3. Calcium entry causes acetylcholine (ACh - a neurotransmitter) to be released by excocytosis. 4. ACh diffuses across the synaptic cleft and binds to its receptors on ...
