The mechanism of skeletal muscle contraction is a process that relies on calcium signaling. However, the physiological role ...

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 engineered mice with a mutation (E3896A) in the RyR1 calcium-binding site, eliminating calcium-induced calcium ...

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 ...

Researchers at Imperial College London have discovered that specialist macrophages—a type of white blood cell—play a key role in the control of muscle contraction and locomotion. The discovery ...

Muscle spasms are the sudden, intense and uncontrollable contraction of muscles. They're painful and frustrating, and can stop athletes in their tracks or jolt someone awake in the middle of the night ...

Though many people experience muscle twitching, it's often incorrectly identified as a muscle spasm. While both are involuntary contractions of a muscle, muscle spasms and muscle twitching aren't ...

Researchers from Harvard and Emory University report that they have developed the first fully-autonomous biohybrid fish from human stem-cell derived cardiac muscle cells. The artificial fish swims by ...

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 ...
