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 ...

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 ...

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.

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 ...

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 ...

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, ...

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

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 ...
