Explain the principles of synaptic transmission
Chemical Synapses
In the synapse, the arrival of an action potential causes a change in membrane permeability for Ca2+ . As a result these calcium ions flow into the synaptic knob.
The consequence of this is exocytosis of a transmitter substance in vesicles.
This neurotransmitter then diffuses across the synaptic cleft and attaches to receptors in…
