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.

As with muscle strength in general, grip strength naturally declines with age, “reflecting changes in muscle mass, neural ...

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 ...

Scientists discover that muscles repair themselves by moving thousands of internal nuclei, a rapid process that is key after ...

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 ...

Your abdominal muscles surround your trunk between the rib cage and pelvis and keep your abdominal organs safe. Your core abdominal muscles also support your trunk and allow movements while keeping ...
