Muscle contraction disease in dogs is a type of seizure. The cause of the condition usually involves a dog’s nervous system. Thankfully, the condition is quite rare in dogs. Also, dogs remain ...

Muscle cells were once thought to be the smallest units that experienced contraction. But new research has suggested that smaller sections of muscles cells can experience localized calcium signaling ...

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, ...

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 ...

Carpopedal spasms are frequent and involuntary muscle contractions in the hands and feet. In some cases, the wrists and ankles are affected. Carpopedal spasms are associated with cramping and tingling ...

Dehydration may be one cause of muscle cramps, and some evidence suggests that electrolyte imbalances also contribute to them. Muscle cramps are painful, involuntary contractions of the muscles that ...

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.
