Can A deficiency of calcium in the body can result in involuntary muscle contractions?
Yes it can
What is the ion called that triggers muscle contractions?
There are several, but a calcium ion is one that is used in skeletal muscle contraction.
Does a deficiency of calcium in the body result in continuous muscle contractions or tetany?

What are the major roles of calcium in the bodes fluids?
Bones are made mostly of calcium compounds and calcium in its' ionic form is important in muscle contractions.
What stores calcium important in muscle contractions?
The Sarcoplasmic Reticulum stores calcium and releases it through the terminal cisternae into the tubule.
What are contract muscles?
Smooth Muscle contractions are regulated by calcium ions. The smooth muscle differs from skeletal muscle in that its contracts from all sides.
What ions serve as a trigger for muscle contractions by removing the inhibition of the troponin molecule?
Calcium ions
What binds calcium ions in a smooth muscle causing contraction?
Contractions are initiated by the calcium-activated phosphorylation of myosin rather than calcium binding to troponin.
Why are calcium ions necessary for skeletal muscle contractions?
calcium increases the action potential transmitted along the scarcolemma
What are smooth muscle contractions?

If a drug caused a sudden release of large amounts of calcium in skeletal muscle from which structure would the calcium come?
The calcium would come from the sarcoplasmic reticulum, which is a specialized structure found within skeletal muscle cells responsible for storing and releasing calcium ions for muscle contraction. A sudden release of large amounts of calcium from the sarcoplasmic reticulum can lead to uncontrolled muscle contractions and potentially muscle damage.
What is it called when an uncontrollable muscle spasm due to overactive neurons caused by lack of calcium?
This condition is called tetany, which is characterized by involuntary muscle contractions caused by decreased levels of calcium in the blood. It can result in symptoms such as muscle twitching, cramps, and spasms.
