Clonus causes involuntary, rhythmic muscle contractions when a muscle is stretched. It is often observed in conditions like multiple sclerosis, stroke, and cerebral palsy. Clonus can be diagnosed by ...

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 early as 1918 Hoffmann described how electrical stimulation of the tibial nerve in man evokes, in addition to a direct motor response in the calf muscles, another well synchronized motor response ...

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 ...

A gelatin memristor with 16 stable conductance states mimics biological pain perception, rating intensity, sensitizing after ...

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, ...

Actomyosin is a protein complex composed of actin and myosin. It is found in muscle fibers where it plays a role in muscle contraction. Actin is one of the most abundant proteins in eukaryotes. It ...

Using powerful new visualization technologies, researchers have captured the first 3-D images of the structure of a key muscle receptor, providing new insights on how muscles develop across the animal ...
