Document Summary

Neural communication: the action potential activates vesicles at axon, vesicles release neurotransmitters across, neurotransmitters cross the synapse and receptors on the dendrites of the next, channels on the post synaptic neuron open action potential to continue, terminating the message don"t want the end of the the synapse bind to neurons and allow the. Nt staying in the synapse long term: reuptake nt gets brought back into the terminal, neurons must be turned on and off, excitatory neurotransmitter nt that causes the receiving cell to fire, inhibitory neurotransmitter nt that causes the receiving cell to stop firing, exogenous chemical substances can also affect neural communication, agonists mimic or enhance the effect of a nt on the receptor, antagonists block or reduce a cell"s response to the action of other chemicals or neurotransmitters, summary, communication between neurons uses chemicals (neurotransmitters, release of neurotransmitters is triggered by an action potential.
