Let’s now trace the entire series of events through a three-neuron loop, including the steps of synaptic transmission between neurons 1 and 2, the propagation of the action potential down the axon of neuron 2, and the steps of synaptic transmission that occur between neuron 2 and 3. Hints are included to ensure that you stay on the right track as you trace. You may wish to consult your textbook for more details on this process. When you have completed the activity answer Check Your Understanding questions 5 through 7 (p. 332) Start: neuronal action potential reaches the axon terminal of neuron 1 from the axon terminal by are released diffuse across the and bind to on the postsynaptic membrane of neuron 2, generating an excitatory local potential ->if the neuron is stimulated enough times, the excitatory local potentials toward the axon when the trigger zone is depolarized to and spread through the neuron’s plasma membrane, an is generated, which down the axon until it reaches the axon terminals depolarization of the axon terminal triggers the opening of ion channels, and these ions enter the axon terminal diffuse are released from the axon terminal by across the on the postsynaptic membrane of neuro and bind to n 3, generating an excitatory or inhibitory local potential.
