| The
Chemical Synapse |
|
|
|
| 1) Nerve impulse |
||
| arrives causing |
||
| influx of Ca+2 |
||
|
|
|
|
|
|
| 5)
Neurotransmitter is |
|||||
| broken down or
removed |
|||||
| from the synapse
to allow |
|||||
| the next
transmission. |
|||||
| ACh-ase, MAO |
|||||
| Reuptake |
|||||
|
|
|
| 2) Ca+2
promotes |
||
| the exocytosis of |
||
| synaptic
vesicles. |
||
|
|
|
|
|
| 3)
Neurotransmitter |
||||
| diffuses across
the |
||||
| synapse to attach |
||||
| to postsynaptic |
||||
| receptors. |
