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,
