Hypomagnesemia

Question: Why does hypomagnesemia cause tetany? I understand how magnesium deficiencies can occur, etc., but I'm looking for a resource about the physiological effects on the nervous system. Specifically, the actions that might occur around the chemical synapse to produce muscle spasms. I've found a lot of information about how calcium plays a role, but not much about magnesium. Does anyone have a good website I can go to? I know how to look on Wikipedia, and the information I need is not in their articles. I need a research reference or scientific paper/study report.

Answer: Hypomagnesemia is plasma Mg concentration < 1.4 mEq/L (< 0.70 mmol/L). Causes include inadequate Mg intake and absorption or increased excretion due to hypercalcemia or drugs such as furosemide. Clinical features are often due to accompanying hypokalemia and hypocalcemia and include lethargy, tremor, tetany, seizures, and arrhythmias. Treatment is with Mg replacement.
