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.

Skeletal muscles are built from small contractile units, the sarcomeres. They are connected in a well-ordered series to form myofibrils that span the entire muscle. Contractions of these sarcomeres ...

Numerous motor and structural proteins compose a highly ordered structure known as the sarcomere, the basic unit of muscle contraction in heart and skeletal muscles. Sarcomeric myosin heavy chain ...

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 ...

Fleeing animals, human athletes and non-athletes alike have experienced skeletal muscles giving out during those intense efforts when they are needed most, whether running for survival, the finish ...

Engineers at Washington University in St. Louis have developed a new class of protein-based fibers modeled on the aligned ...

Beet juice boosts endurance for many (but not all) people, according to a series of studies over the past five years or so. The active ingredient appears to be nitrate, which somehow reduces the ...

Skeletal muscle is the type of muscle that controls movement. Problems with these muscles can be minor, life-threatening, or ongoing problems that make it hard to perform basic daily activities.

Since statins first came to market in the late 1980s, muscle aches, weakness, and fatigue have driven many patients to ...

IS OUR PURELL KILLING US? No. Interestingly, though, the common soap/deodorant/cleaner ingredient triclosan has been found to impair muscle function. There is now one more reason for people to break ...
