WebCalcium (Ca 2+) is a vital element in the process of neurotransmitter release; when Ca 2+ channels are blocked, neurotransmitter release is inhibited. When the action potential reaches the nerve terminal, voltage-dependent Ca 2+ channels open and Ca 2+ rushes into the neuron terminal due to a greater extracellular concentration. cindy williams family picturesWebSupplying the cell For an organism to function, substances must move into and out of cells.
