The contraction of smooth muscle is an essential process underpinning diverse physiological functions ranging from gastrointestinal motility to vascular regulation. At its core, smooth muscle ...

In a serendipitous discovery, UC San Diego researchers using cryo-EM technology captured the first visualizations of the 3-D structure of the muscle acetylcholine receptor in fetal and adult muscles.

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 ...

Atomic images of muscle molecules in action have now been captured by researchers, giving possibility of new nanomachines. At the molecular level, muscle contraction is defined by myosin molecules ...

The connections between the nervous system and muscles develop differently across the kingdom of life. It takes newborn humans roughly a year to develop the proper muscular systems that support the ...

At one point or another, we’ve all experienced the unexpected, intense pain of a muscle cramp. Muscle cramps, also known as muscle spasms or charley horses, are the involuntary contraction of muscle ...

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 ...

A group of researchers led by Specially Appointed Assistant Professor FUJII Takashi and Professor NAMBA Keiichi unraveled the three-dimensional structure of actomyosin rigor complex (complex of actin ...
