Calcium’s Vital Role in Neurotransmission

Calcium is crucial for neural signaling, making it vital for all our brain and body’s processes.
Neurotransmitters are stored in vesicles at the end of neurons' axons. When a neuron is activated, calcium rushes inside and causes the vesicles to fuse with the axon membrane, releasing their neurotransmitters into the synapse. So, if calcium is too low, neural signaling will weaken or even fail. But neurons beware, it’s all about balance - too much calcium can be toxic.
