Calcium Channel = Protein channels in the membrane that allow Calcium to come into the axon terminal.
Pre-Synaptic Neuron = The neuron who transmits the signal to another neuron (axon terminal of the first neuron).
Post-synaptic Neuron = The neuron that receives the signal (the dendrite of the next neuron).
Neurotransmitter = the chemical that is released between two neurons to transmit the signal.
Explain how a neural signal is communicated across a synapse.
Draw and label this whole pic!
INITIATION: The electric signal reaches the axon terminal of the presynaptic neuron.
RELEASE: The electric signal causes the synaptic vesicle to fuse with the membrane, releasing neurotransmitters into the synaptic cleft
BINDING: Neurotransmitters bind to the receptors on the postsynaptic neuron.
EFFECT: Binding of neurotransmitters to the postsynaptic neuron causes a change in the postsynaptic neuron. For example, it may cause the signal to continue to the next neuron or to stop.
REMOVAL: The neurotransmitters are either recycled, removed, or deactivated from the synaptic cleft.
Presynaptic neuron (axon terminal)
Postsynaptic neuron (dendrite)
