Your every move, from blinking to sprinting, depends on the neuromuscular junction (NMJ) — the tiny but powerful meeting point between nerve and muscle. Here, electrical signals transform into ...

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.

From the microscopic dance of actin and myosin to the full-body power you feel in a workout, muscle contraction is a precise, coordinated process. It starts with a nerve signal, triggers calcium ...

Research has uncovered how motor protein myosin, which is responsible for contraction of skeletal muscles, functions also in non-muscle cells to build contractile structures at the inner face of the ...

In a new research report, a team of scientists led by Johns Hopkins Medicine say people with severe obesity and a common type ...
