Neurotransmission the essentials Parts of a Neuron

1 Axon Neurotransmitters Calcium 2+ synapse Receptors presynaptic neurone

2 Action potential Neurotransmitters

3 Neurotransmitters As active potential goes down axon, the charges become opposite

4 Neurotransmitters Depolarization

5 Neurotransmitters Depolarization

6 Neurotransmitters Depolarization

7 Neurotransmitters

8 Neurotransmitters altered membrane potential allows calcium ions to enter the presynaptic neurone

9 Neurotransmitters

10 Neurotransmitters

11 Neurotransmitters

12 increase in Ca++ levels in side the cell triggers the fusion of pocket containing neurotransmitters with the presynaptic neuron membrane Neurotransmitters

13 Neurotransmitters

14 When the neurotransmitters leave, the change in the synapse goes back to normal Neurotransmitters

15 Neurotransmitters have specific receptors Neurotransmitters
