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.

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 the molecular level, muscle contraction is defined by myosin molecules pulling actin filaments. New electron cryomicroscopy images with unprecedented resolution taken by researchers at Osaka ...

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, ...

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 biology behind muscle pain: calcium chaos, microscopic damage, and the overlooked mechanism that explains how statins can quietly affect muscle from the inside out.

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.

Electrical muscle stimulation involves sending electrical impulses through the skin. This stimulation may provide benefits, such as helping to repair tissue and strengthen muscles. The electrical ...
