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 ...

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 ...

Segments of the obliquely striated body muscle of Ascaris were fixed at minimum body length after treatment with acetylcholine and at maximum body length after treatment with piperazine citrate and ...

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 ...

Research has uncovered how motor protein myosin, which is responsible for contraction of skeletal muscles, functions also in non-muscle cells to build contractile structures at the inner face of the ...

Physical forces from gravity, muscle contraction, and more have strong impacts on how the cells in our bodies behave. For instance, weight-bearing exercise helps stave off osteoporosis because cells ...

Researchers identified a critical AMPK phosphorylation site that regulates mitochondria, muscle contraction, and sugar ...

If you enjoyed this article, I’d like to ask for your support. Scientific American has served as an advocate for science and industry for 180 years, and right now may be the most critical moment in ...

Skeletal muscle is the most abundant tissue of the human body (about 40%) and it plays essential role in locomotion and vital functions (heart rate, breathing). During aging, in a large majority of ...
