Critical Vocabulary- Top of Pg. 82
Please write down vocabulary and draw a picture to remind you of what the word means.
Synapse = Place where the 2 neurons meet. It includes the receptors of the 2 neurons along with the synaptic cleft.
Synaptic Cleft = The space in between the axon terminal and the dendrite of two neurons.
Synaptic vesicle = Packaged ball of neurotransmitters.
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.
How do you communicate to your friend in Texas, without any technology?

Directions
• Part 1: Arrange the pictures in order the order of the pictures on your sheet. Then, arrange the written descriptions in order. Try to match the description with its picture.
• Part 2. Label the following parts of the picture below: presynaptic neuron, postsynaptic neuron, neurotransmitter, postsynaptic receptor, neurotransmitter transporter, synaptic vesicle
Draw and label this whole pic!
Investigate on Your Own- Pg. 84

Get Ready for Notes Pg. 82-83Title: Synaptic Transmission
Step 1
INITIATION: The electric signal reaches the axon terminal of the presynaptic neuron.
Initiation Release Binding Effect Removal
Step 2RELEASE: The electric signal causes the synaptic vesicle to fuse with the membrane, releasing neurotransmitters into the synaptic cleft
Initiation Release Binding Effect Removal
Step 3
BINDING: Neurotransmitters bind to the receptors on the postsynaptic neuron.
Initiation Release Binding Effect Removal
Step 4EFFECT: 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.
Initiation Release Binding Effect Removal
Step 5REMOVAL: The neurotransmitters are either recycled, removed, or deactivated from the synaptic cleft.
Initiation Release Binding Effect Removal
