Objectives
? Review the Synapse ? Discuss some drugs and their effects on the
synapse ? Discuss how the altered synapses may
affect the adolescent brain ? Play "Jeopardy Game" on neurobiology
Review the Synapse
? What is a synapse?
? A synapse is the "gap" between the axon of one nerve and the dendrite of the next one.
? The average neuron has 1,000 synapses with other neurons.

Figure 48.12 A chemical synapse
Key to Previous Diagram
1. Impulse from action potential opens ion channels for Ca++
2. The increased Ca++ concentration in the axon terminal initiates the release of the neurotransmitter (NT)
3. NT is released from its vesicle and crosses the "gap" or synaptic cleft and attaches to a protein receptor on the dendrite
Key to Diagram (cont.)
4. Interaction of NT and protein receptor open post-synaptic membrane ion channel for Na+
5. After transmission the NT is either degraded by an enzyme or taken back into the pre-synaptic membrane by a transporter or reuptake pump
