What does calcium do at the axon terminal? When the action potential reaches the terminal, it activates voltage-dependent calcium channels, allowing calcium ions to flow into theterminal. In the resting state, neurotransmitters are stored in vesicles at the pre-synaptic terminal.
What does calcium do in an action potential? A critical component of the action potential is the rise in intracellular calcium that activates both small conductance potassium channels essential during membrane repolarization, and triggers transmitter release from the cell.
What does calcium do in neurons? In neurons calcium plays a dual role as a charge carrier and an intracellular messenger. Calcium signals regulate various developmental processes and have a key role in apoptosis, neurotransmitter release and membrane excitability.
What does the flow of calcium into the axon cause? The intracellular calcium influx causes synaptic vesicles containing neurotransmitter to fuse with the presynaptic membrane. The neurotransmitter diffuses across the synaptic cleft and binds to receptors on the postsynaptic membrane.
