Synapse Signaling

Neurotransmitters are released from the

• Dendrites

• Post-synaptic neuron

• Presynaptic neuron

• Schwann Cells

In order for a neuron to have an action potential, the neuron must receive more

• excitatory neurotransmitters
• inhibitory neurotransmitters
• agnostic neurotransmitters
• antagonistic neurotransmitters

Excess neurotransmitters in the synapse that goes back into the presynaptic neuron.

• Resting potential
• Reuptake
• Retroactivity
• Repolarization

W

• Axon Terminal Button

• presynapse

• post synapse

• Synapse

Y

• Axon Terminal Button
• Neurotransmitters
• Dendrite
• Synapse

What generates a nerve impulse on the post-synaptic membrane? 

• Calcium binding with a receptor site
• Potassium leaking into the post-synaptic membrane 
• Neurotransmitter binding with receptor sites
• Neurotransmitter being removed from the synapse
