Document Summary

The small space btwn the terminal button and the neuron it is communicating with (any part of neuron not just dendrites) terminal buttons. Synaptic transmission is the primary means of communication btwn neurons. Messages are carried by neurotransmitters(nt) that are released by the. Number of synaptic connections on each neuron varies greatly. The membrane of a terminal button that lies adjacent to the postsynaptic membrane. The membrane on the cell that receives the message that is opposite the terminal button. Small round or oval hollow structures that contain molecules of chemical messenger. An ap is conducted down an axon to the terminal buttons. The ap triggers the synaptic vesicles to fuse with the membrane. The fusion causes the release of chemical messenger into the synaptic cleft. The chemical messenger diffuses across the synapse to the postsynaptic membrane. Nt is often synthesized in the axon terminal which get packaged into vesicles that wait to be released.
