The condition resulting in muscle spasms due to an abnormally low concentration of calcium in the blood is tetany.
What is tetany?
- Tetany is a condition marked by muscle spasms at irregular intervals. It is an involuntary muscle contraction.
- This is caused due to the defect in parathyroid glands resulting in deficiency of calcium in the blood.
- Muscle spasms are caused due to poor communication between neurons.
- As calcium is released as a neurotransmitter at the point of contact between two neurons (synapse), its deficiency prevents the transfer of signal from one neuron to the other resulting in muscle spasms.
- Tetany may lead to seizures, painful muscle cramps, numbness in feet and hands, heart problems, spasms of voice box.
