Generally, calcium ion exists either free or unattached to various plasma proteins. There's about an equal concentration of free and bound calcium in body tissues. Of course, as you know, calcium ion plays important roles in blood clotting, neurotransmitter release (the topic you're asking about), muscle tone, etc.

    The amount of calcium ion that enters the neuron to ...
