IT is generally believed that the process which initiates contraction in striated muscle is the depolarization of the excitable membrane of the muscle fibre, although the mechanism by which membrane ...

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 ...

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 ...

Researchers at UT Southwestern Medical Center at Dallas are the first to use genetically engineered mice containing a fluorescent molecule to examine in real time the chemical reactions that result in ...

DALLAS – April 5, 2004 – Researchers at UT Southwestern Medical Center at Dallas are the first to use genetically engineered mice containing a fluorescent molecule to examine in real time the chemical ...

Muscle contraction is the tightening, shortening, or lengthening of muscles when you do some activity. It can happen when you hold or pick up something, or when you stretch or exercise with weights.

Molecular discoveries may help improve treatments for labor and pain. When labor starts, the uterus must produce steady, ...

A concentric contraction is a type of muscle activation that causes tension on your muscle as it shortens. As your muscle shortens, it generates enough force to move an object. This is the most ...

It is a marvel of nature: during gestation, multiple tissue types cooperate in building the elegantly functional structures of organs, from the brain’s folds to the heart’s multiple chambers. A recent ...

Researchers at the University of Vermont College of Medicine have made a discovery that helps explain how we know when to empty our bladders and may lead to new therapeutic interventions for bladder ...
