Calcium binding to actin-myosin causes contraction. The calcium is released to the sarcomere from a specialized storage organelle, the sarcoplasmic reticulum.

What is an important ion for muscle contraction?
calcium
What ion is necessary for cardiac contraction to occur?
calcium is te most important ion in cardiac contraction , whereas the contraction starts by the Na .
What happens if your calcium ion concentration drops by 50 percent?
In all likelihood you would die as calcium is essential for both muscle contraction and nervous system communication.
What is the ion necessary in cross bridging to produce a muscle contraction is?
calcium
What ion initiates muscle contraction?
when you are working out and you are lifting a weight....
Are sodium and potassium the final go signal in muscle contraction?
an increase in intracellular calcium ion levels
In muscle contraction calcium apparently acts to?
Muscle contraction is regulated by calcium ions, which will change thin filament into an activated state by binding to troponin. The binding of calcium to the troponin changes it's shape so the myosin binding sites on the actin (thin filament) are exposedbind to regulatory sites on troponin to remove contraction inhibition
What inhibits muscular contraction?
Muscle fatigue has a number of causes including ion imbalance within the muscle or nervous fatigue. And most importantly, from the accumulation of lactic acid in the muscle.
Cross-bridge formation that results in muscle contraction requires intracellular?
the major intracellular ion in crossbridge formation is what
Which protein inhibits skeletal muscle contraction and what ion removes the inhibition?
Tropomyosin; calcium ions
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.
Whats the name of the chemical in the muscular system that causes contraction?
There's more than one chemical that causes contraction. The neurotransmitter (usually acetylcholine) is released from the nerve and excites the muscle. There is a change in calcium, sodium and potassium ion concentrations. ATP is used. All of these work together to produce a muscle contraction.
