1. Action potential reaches the axon terminal and depolarizes it.
2. Depolarization opens voltage-gated calcium channels, enabling influx of Ca into the neuron.
3. Calcium binds to specialized proteins on vesicles (containing pre-made acetylcholine) and triggers them to fuse with the neuron membrane at the synapse.
4. Exocytosis of acetylcholine into the synaptic cleft occurs.
5. Acetylcholine diffuses across the synapse and binds to nicotinic receptors on the end plate of the myocyte.
6. Activated nicotinic receptors, themselves ion channels, cause cation influx into the myocyte and generate an end plate potential. This eventually gives rise to the full depolarization within the myocyte that enables contraction.
The first one according to the graph

here is what I know about earthquakes..
Explanation:
Learn how to prepare for an earthquake with the following safety tips. Please review our guidance on preparing for an earthquake while still protecting. Doorways are no stronger than any other part of a structure so don't rely on them for protection! Staying informed about your community's risk and response plans.
