TerminalButtons
DendritesExcitatory: Continue the action potential
TerminalButtons
Dendrites
Inhibitory: End the action potential
Both kinds received at once
Excitatory has to pass a certain threshold to create an Action potential
Excitatory or Inhibitory?
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
Neurotransmitters
BOTOX
BOTOX
Inhibits
Acetylcholine
Acetylcholine is the neurotransmitter, which, when abundant in our
muscle synapses, control muscle movement
BOTOX
keeps acetylcholine out of the synapse
So the muscles that cause
wrinkles are temporarily paralyzed
