Researchers were able to control heart muscle function in a new way after discovering the previously unknown role of two enzymes in heart muscle contraction. Although in the early stages, the research ...

Muscle cramps are a common and often uncomfortable phenomenon that many individuals experience. These sudden, involuntary contractions can occur in various muscle groups, causing sharp pain and ...

The sarcomere is the most basic contractile unit in skeletal and cardiac muscle. Mutations in genes encoding sarcomeric proteins give rise to heritable myopathies, although muscle function is more ...

A new molecular pathway has been identified that is critical for maintaining the smooth muscle tone that allows the passage of materials through the digestive system. Researchers at UMass Medical ...

IT is well established that an increase in the intracellular concentration of ionized calcium after excitation in the membrane is the key factor for initiation of contraction of various types of ...

The contractile responses of esophageal smooth muscle (SM) induced by platelet-activating factor (PAF) involve the activation of L-type voltage-dependent calcium channels (L-type VDCCs), ...

Muscle cramps are involuntarily contracted muscles that do not relax The slight contraction of muscle is spasm A muscle cramp can last for about a fraction of seconds to about an hour One of the major ...

You’re relaxing on the sofa when suddenly your eyelid starts twitching. Or perhaps it’s a muscle in your arm, your leg, or your foot that begins to spasm – sometimes for a few seconds, sometimes for ...
