The flow of water within a muscle fiber may dictate how quickly muscle can contract, according to a University of Michigan study. Nearly all animals use muscle to move, and it's been known for a long ...

Calcium ions orchestrate contraction and relaxation in airway smooth muscle by regulating excitation–contraction coupling. In quiescent cells, basal cytosolic Ca2+ is maintained at nanomolar levels by ...

The mechanism of skeletal muscle contraction is a process that relies on calcium signaling. However, the physiological role of calcium-induced calcium release (CICR) through the ryanodine receptor ...
