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.

Muscle contraction is the tightening, shortening, or lengthening of muscles when you do some activity. It can happen when you hold or pick up something, or when you stretch or exercise with weights.

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 ...

A gelatin memristor with 16 stable conductance states mimics biological pain perception, rating intensity, sensitizing after injury, and self-healing while directly controlling mouse muscle response.

Minor muscle spasming can occur due to health conditions like nutrient deficiencies. More severe twitching can be a symptom of serious health conditions, including those affecting the nervous system.

Muscles and nerve fibers allow a person to move their body and enable the internal organs to function. There are more than 600 muscles in the human body. People also have different types of muscle. A ...

Time under contraction is not directly measured in a typical weight training program. Most people really don't even think about the number of seconds a given muscle is forced to work. Indirectly, ...

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 ...
