1
step 1
action potential that occurred in the presynaptic cell reaches the presynaptic terminal
2
step 2
calcium anion from the extra cellular fluid goes into the presynaptic cell
3
step 3
the synaptic vesicles release its context (neurotransmitters)into the synaptic cleft, utilizing energy from the mitochondria
4
step 4
the neurotransmitters from the synaptic cleft attaches to the receptors of the post synaptic terminal
5
step 5
change in the cell membrane permeability of the post synaptic cell
6
step 6
if the membrane become more permeable to Na+ it will move out to in, thus making the inside less negative
7
step 7
if it touches the threshold it lead to an action potential in the post synaptic cell.
