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.

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 ...

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 ...

The connections between the nervous system and muscles develop differently across the kingdom of life. It takes newborn humans roughly a year to develop the proper muscular systems that support the ...

Transverse tubules (T-tubules) play significant role in muscle contraction. However, the underlying mechanism of their formation is yet to be ...

Time under tension (TUT) is a weightlifting technique designed to build muscle mass by increasing the time muscles spend activated during an exercise. We cover if it works and what its benefits are.
