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.

The effect was specific to fast-twitch fibers, which are used to generate rapid, powerful movements like sprinting and ...

The muscular system consists of various types of muscle that each play a crucial role in the function of the body. Some muscular system functions include mobility, stability, posture, and circulation.

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.

The mechanism of skeletal muscle contraction is a process that relies on calcium signaling. However, the physiological role of calcium-induced calcium release (CICR) through the ryanodine receptor ...

Muscles play a part in every function of the body. The muscular system is made up of over 600 muscles. These include three muscle types: smooth, skeletal, and cardiac. Only skeletal muscles are ...

Autoimmune neuromuscular diseases may sound complex, but understanding them is the first step to getting the right care and ...

Accomplishing perhaps a world first, researchers at Columbia University and the UChicago-affiliated Marine Biological Laboratory have mapped the full-body muscular activity of an animal while it was ...

Researchers at the Universities of Maynooth and Bonn discover a new connection in muscular dystrophy Duchenne muscular dystrophy (DMD) is the most common muscle disease in children and is passed on by ...
