chemical synapse, Information is transferred through the release of a neurotransmitter from one neuron and detection of the neurotransmitter by an adjacent cell, excitatory or inhibitory effect, Effect that the relationship between a neurotransmitter and its receptor can cause, first event , Chemical synapse event - Action potential arrives at the axon terminal, third event, Chemical synapse event - Ca entry causes vesicles filled with neurotransmitters to release their contents by exocytosis, fourth event, Chemical synapse event - Neurotransmitter diffuses across the synaptic cleft and binds to specific receptors on the synaptic membrane, second event, Chemical synapse event - Ca channels open and Ca diffuses into synaptic end bulbs from the ECF, fifth event, Chemical synapse event - Binding of the neurotransmitters opens specific ion channels (Na), causing a change in the membrane potential, sixth event, Chemical synapse event - Neurotransmitter effects are terminated, structure of chemical synapse, The image corresponds to the, calcium, Without _______________ ions trigger the release of neurotransmitter from synaptic vesicles into the synaptic cleft, excitatory postsynaptic potential, Postsynaptic potential that makes the postsynaptic neuron more likely to fire an action potential, inhibitory postsynaptic potential, A kind of synaptic potential that makes a postsynaptic neuron less likely to generate an action potential.
