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 ...

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 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, ...

SINCE Lundsgaard showed that the contractile mechanism can work without production of lactic acid and that this acid, when formed, appears mainly, perhaps entirely, after contraction is over, the one ...

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 ...

Transverse tubules (T-tubules) play significant role in muscle contraction. However, the underlying mechanism of their formation is yet to be elucidated. In a recent study, a research team from Japan ...

THE function of the heart is to propel unoxygenated blood to the lungs and to deliver oxygenated blood to the peripheral tissues in accordance with their metabolic requirements. Since William Harvey's ...

Scientists have developed a network of mechanical motors that mimic the molecular machinery underpinning human muscle contraction. The University of Bristol-led findings, published in the Journal of ...

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 ...

The biology behind muscle pain: calcium chaos, microscopic damage, and the overlooked mechanism that explains how statins can ...
