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 ...

As people age, muscles naturally lose mass and strength, a condition known as sarcopenia. The decline can make everyday activities harder and increases the risk of falls, disability and early death.

A team of researchers has developed a simple lab-based system for growing human muscle cells that are capable of vigorously contracting. A team of researchers at Tohoku University have developed a ...

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 ...

Space exploration activity has been increasing. In turn, researchers are more interested than ever in uncovering more about how space travel affects human health and the progression of disease.

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 ...

Medically reviewed by Jennifer Steinhoff, MD Key Takeaways Muscle strength grading helps evaluate muscle strength on a scale ...
