When threshold is reached, what are the roles of calcium ions at the axonal terminal?

What are the functions of the:
1. Neurotransmitter
2. Post synaptic neuron receptors
3. synaptic cleft
4. synaptic vessicles
5. removal of the neurotransmitter
6. Ion channels affected
7. excitation or inhibition of post synaptic neuron

Please be deatiled.

Before even considering of answering these numerous questions, have you given them a thought yourself? Have you tried looking up these processes yourself first? If so, what have you found? If not, why not?

 

Dare I ask what the idea of all these sudden questions are, by the way? Exam coming? Self study? ... ?

 

I mean, I certainly believe you are allowed to, since this is the Homework Help part of the Forums, but your sudden input of lots of questions stimulates my curiosity.

I think a good animation or diagram is better than a hundred words:

Come back after watching it and ask for further help if necessary.
