Calcium is a key factor in normal transmission of nerve impulses. The movement of calcium into nerve cells triggers the release of neurotransmitters at the junction between nerves.
The calcium appeared to aid the momentary fusion of the vesicle membrane and the nerve fiber membrane, prior to the bursting open of the vesicle.
The neuron releases neurotransmitters in direct proportion to the number of calcium ions that flow through the cell’s calcium channels.
Neurotransmitters are released into the synaptic cleft. They migrate to the membrane of the plasma membrane of the postsynaptic neuron where they bind to receptors embedded on the membrane.
Insufficient calcium can inhibit nerve transmissions. It can act as an anesthetic to dull nerve impulses.
