Two hitherto unknown enzymes play a key role in regulating the mechanism behind heart muscle contraction, a research team led by an Indian-origin researcher, has revealed.

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 ...

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

Researchers describe a new mechanism for muscle repair after physiological damage relying on the rearrangement of muscle fibre nuclei, and independently of muscle stem cells.

Muscle is known to regenerate through a complex process that involves several steps and relies on stem cells. Now, a study has described a mechanism for muscle repair after physiological damage, ...

Learn more about the different types of muscle contractions, how to do them, what they’re used for, and the benefits.

There are major shifts underway in understanding the physiological mechanisms that control muscle contraction, a field that has been the focus of intense research for centuries. A new article ...

In a new study, UT Southwestern researchers report that one set of chemical reactions resulting in the contraction of the smooth-muscle cells is augmented by a second chemical pathway that kicks ...

Numerous motor and structural proteins compose a highly ordered structure known as the sarcomere, the basic unit of muscle contraction in heart and skeletal muscles. Sarcomeric myosin heavy chain ...
