The mitochondria is the organelle that provides the energy needed for muscle contraction through the production of adenosine triphosphate (ATP), which is the energy currency of the cell.

Asystole means without contraction of the heart. Atony is a term used to denote no normal muscle contraction of the uterus.
The normal gene is responsible for a muscle protein controlling the flow of sodium during muscle contraction.
The normal gene is responsible for a muscle protein controlling the flow of calcium during muscle contraction.
It increases about to about four times greater than a normal contraction for skeletal muscle.
Contraction is the medical term meaning the normal shortening or tightening of a muscle.
During the latent period of muscle contraction Ca++ is being released from the sacroplasmic reticulum and filament movement is taking up slack. This takes approx. 2 milliseconds.
Angiospasm is sudden contraction of a blood vessel. In contrast, vasoconstriction is the normal process of contraction of a blood vessel.VasoconstrictionAngiospasm
Organopesticides will increase the severity of muscle contraction beyond normal conditions. Acetylcholine esterase inhibition will allow a more than normal amount of acetylcholine to bind to receptors.
I bleive the answer you are looking for is "minerals". for instance bone and teeth require Calcium.
The state of partial skeletal muscle contraction is known as tonus. Muscles of the body do not have a real state of total relaxation.
