Neuron
Drugs have their effects because they
mimic some neurotransmitters
cause neurotransmitters to be released without a signaling action potential
block the re-uptake of some neurotransmitters
cause action potentials to move in reverse along the axon
In the presence of calcium ions, synaptic vesicles fuse to synaptic knob membrane
The added membrane provides material for endocytotic vesicles
Action potential passes along an axon and over the surface of its synaptic knob
Synaptic knob membrane becomes more permeable to calcium ions, and they diffuse inward.
Synaptic vesicle membrane becomes part of the cell membrane and Synaptic vesicles release their neurotransmitter by exocytosis into the synaptic cleft
