In tetany hyperexcitability is due to:
Ans. (a) Low Ca++ causes | permeability to Na+(Ref: Ganong, 25th ed/p.380)Reason for hyperexcitability in tetany - low serum calcium levels moves more sodium ions entry into the cell leading to more frequent action potential generation
Low Ca++ causes | permeability to Na+
Prevent k+ release
Prevent Na+ & K+ release
|Ca++ produce generation of AP
