5. 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.

6. Explain how a neural signal is communicated across a synapse.

7. How do you communicate to your friend in Texas, without any technology?

19. A. IBE Directions- Do under your catalyst 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!

21. Get Ready for Notes Pg. 82-83 Title: Synaptic Transmission

22. Step 1 INITIATION: The electric signal reaches the axon terminal of the presynaptic neuron. InitiationReleaseBindingEffectRemoval

23. Step 2 RELEASE: The electric signal causes the synaptic vesicle to fuse with the membrane, releasing neurotransmitters into the synaptic cleft InitiationReleaseBindingEffectRemoval

24. Step 3 BINDING: Neurotransmitters bind to the receptors on the postsynaptic neuron. InitiationReleaseBindingEffectRemoval

25. Step 4 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. InitiationReleaseBindingEffectRemoval

26. Step 5 REMOVAL: The neurotransmitters are either recycled, removed, or deactivated from the synaptic cleft. InitiationReleaseBindingEffectRemoval
