The Neuron: Structure and Function of Dendrites, Axons, Synapses and Neurotransmitters

1. You Have Some Nerve

2. The Neuron

3. Dendrites Dendrites

4. Dendrites Dendrites Cell

5. Dendrites Dendrites Cell Axon

6. Dendrites Dendrites Cell Axon Terminal Buttons

8. Synapse

9. Presynaptic Neuron

10. Presynaptic Neuron Lots of chemical activity

11. Post Synaptic Neuron

12. The Action Potential

13. Th Action Potential

21. Terminal Buttons Dendrites

23. Terminal Buttons Dendrites Neurotransmitter Receptor

30. Terminal Buttons Dendrites Excitatory: Continue the action potential

31. Terminal Buttons Dendrites Inhibitory: End the action potential

32. Excitatory or Inhibitory? Both kinds received at once Excitatory has to pass a certain threshold to create an Action potential

34. Neurotransmitters Acetylcholine Present in the synapses in the nerves at our muscles. More Acetycholine in the synapse: Binds with receptors at the dendrite to effect an action potential, and thus, create muscle movement Less acetylcholine in the synapse: no action potentials...no muscle movement

35. Neurotransmitters BOTOX

37. BOTOX Inhibits Acetylcholine

38. Acetylcholine is the neurotransmitter, which, when abundant in our muscle synapses, control muscle movement

39. BOTOX keeps acetylcholine out of the synapse

40. So the muscles that cause wrinkles are temporarily paralyzed
