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 ...

It is important to understand the principles of normal neuromuscular transmission when using neuromuscular blocking agents. The neuromuscular junction consists of the motor-nerve terminus, the ...

New research has shown one type of muscle contraction is most effective at increasing muscle strength and muscle size -- and rather than lifting weights, the emphasis should be on lowering them. Good ...

Muscles move our bodies. To do so, they contract, which then generates movement. Share on Pinterest Muscles use energy from our food to produce movement. Muscles allow us to consciously move our limbs ...

A new study suggests severe obesity may weaken heart muscle cells in people with heart failure with preserved ejection ...

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 ...
