Researchers were able to control heart muscle function in a new way after discovering the previously unknown role of two enzymes in heart muscle contraction. Although in the early stages, the research ...

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 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, ...

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.

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 film discusses the intricate relationship between muscles and bones, highlighting the mechanics of body movement. It explains how muscles work by contracting and relaxing in coordination with ...
