7 steps action potential

STUDY
PLAY
1
The action potential arrives at the axon terminal
2
Calcium channels open allowing calcium ions to enter the axon terminal
3
Acetylcholine is released into the synaptic cleft and calcium ions are pumped out of the axon terminal
4
Acetylcholine binds to receptor sites on the motor end plate
5
An action potential is generated which propagates and travels down t-tubulues
6
The action potential causes the release of calcium ions
7
Calcium ions trigger a contraction of the muscle cell
