What is Neurotransmission?:  Neuron → Neuron/Cell/Organ/Muscle/Etc. Communication  Point of ‘Communication’ = The “Synapse” Terminology:  Pre-Synaptic Neuron: The ‘Sender’ Neuron  Synaptic Cleft: The ‘Gap’ Between cells  Post-Synaptic Cell: The ‘Receiver’ Cell  Synaptic Potential: The ‘Drive’ for Transmission (that mobilizes the synaptic vesicles to pre-synaptic membrane). Neuron-Neuron Neurotransmission:  Note: Neurons Synapse with Each ...
