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 ...

Within every muscle of every living species with a backbone, a protein called myosin tugs on a partner protein to generate a ...

A Northwestern Medicine study has uncovered how chronic defects in muscle membrane repair can fuel harmful inflammation. The ...

In a serendipitous discovery, UC San Diego researchers using cryo-EM technology captured the first visualizations of the 3-D structure of the muscle acetylcholine receptor in fetal and adult muscles.

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 ...

A research group has uncovered important details about how platelet-activating factor (PAF)—a powerful molecule involved in inflammation and allergic reactions—triggers contractions in the smooth ...

Movement defines life across the animal kingdom. From a fish cutting through water to a bird taking flight, muscles power ...
