calcium influx
Mineral entering cells
Calcium influx is the movement of calcium ions into a cell, typically through specialized channels in the cell membrane.
This flow triggers essential biological processes—muscle contraction, neurotransmitter release, hormone secretion.
In neuroscience and cardiology, controlling calcium influx is crucial: Calcium channel blockers reduce calcium influx to lower blood pressure.
