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 ...

The flow of water within a muscle fiber may dictate how quickly muscle can contract, according to a new study. The flow of water within a muscle fiber may dictate how quickly muscle can contract, ...

Sometimes, people experience random muscle twitches that interrupt their normal daily activities. This is usually not harmful ...

Using powerful new visualization technologies, researchers have captured the first 3-D images of the structure of a key muscle receptor, providing new insights on how muscles develop across the animal ...

The Nature Index 2025 Research Leaders — previously known as Annual Tables — reveal the leading institutions and countries/territories in the natural and health sciences, according to their output in ...

In healthy people, binding of the molecule acetylcholine (ACh) to its receptor (AChR) on skeletal muscle cells triggers muscle contraction underlying regular daily activities. In the autoimmune ...

At one point or another, we’ve all experienced the unexpected, intense pain of a muscle cramp. Muscle cramps, also known as muscle spasms or charley horses, are the involuntary contraction of muscle ...

Dystonia is a neurological disorder causing involuntary muscle contractions and abnormal postures. Botulinum toxin (e.g., Botox) is the gold-standard, first-line treatment for focal dystonias, which ...
