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.

From the microscopic dance of actin and myosin to the full-body power you feel in a workout, muscle contraction is a precise, coordinated process. It starts with a nerve signal, triggers calcium ...

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 ...

Researchers have uncovered the detailed shape of a key protein involved in muscle contraction. Researchers at UT Southwestern Medical Center have uncovered the detailed shape of a key protein involved ...

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, ...

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.

A research team at IMEC in Belgium has developed a lens-free microscope that shows cardiac cells starting to contract and "beat" spontaneously. Veerle Reumers, a biomedical engineer at the research ...
