Researchers were able to use light to induce normal patterns of muscle contraction, in a study involving bioengineered mice whose nerve-cell surfaces are coated with special light-sensitive proteins.

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.

WHEN nerve impulses bring about the development of tension in a muscle, depolarization of the muscle fibre membranes can be observed. The question arises: Is this depolarization directly responsible ...

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.

Researchers have discovered the mechanism that facilitates how two ion channels collaborate in the control of electrical signals in the brain. The investigators showed that the channels were anchored ...

Regular activity not only strengthens muscles but can bolster our bones, blood vessels, and immune system. MIT engineers have now found that exercise can also have benefits at the level of individual ...

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.
