Step 1
Step 1: In non-activated cells, calmodulin would not be activated to bind to calcium ions, therefore not sequestering them and leading to high cytosolic levels of calcium ions. Show more…

When voltage-gated calcium ion channels open at the synaptic terminal: a. calcium ions exit the cell, which repolarizes the membrane and resets the resting membrane potential. b. calcium ions rush into the neuron, depolarizing the membrane and triggering an action potential. c. calcium ions rush into the presynaptic neuron, which causes synaptic vesicles to release neurotransmitter into the synaptic cleft. d. voltage-gated sodium channels on the postsynaptic neuron open, which triggers an action potential if threshold is reached

Calcium levels in the extracellular fluid affect neuronal excitability via calcium-mediated calcium release from the endoplasmic reticulum, insertion of receptors for parathyroid hormone into the plasma membrane of the neuron, the extent to which they enter the cell through leak calcium channels, and their effect on sodium permeability of the plasma membrane of the neuron.
