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.
